JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD 100mA Fixed Output Three Terminal Positive Regulators CJ78L Series 1 Three Terminal Positive Regulators Introduction The CJ78L series is a three terminal positive voltage linear regulator with fixed voltage output. It has a wide input voltage range. The maximum input voltage can reach 30V (or 35V). At the same time, it can also provide 100mA output current under the condition of good heat dissipation. The CJ78L series adopts fixed voltage output without peripheral resistance, which improves the space utilization efficiency of printed circuit board (PCB). In addition, the CJ78L series also integrates internal current limit, short-circuit protection and thermal shutdown, so that it is basically not affected by overload. Therefore, the CJ78L series is widely used in various scenarios, such as card supervision, to eliminate the noise and distribution problems related to single point supervision. When used as a substitute for Zener-diode resistor combination, it can effectively improve the output impedance and reduce the bias current. 3 Features  Available Output Voltage: 5.0V, 6.0V, 8.0V, 9.0V, 12V and 15V Maximum Input Voltage: 30V for VOUT < 10V 35V for VOUT > 10V   Maximum Output Current: Exceed 100mA Output Tolerances: ±3% at TJ = 25°C ±5% over the Operating TJ     Build-in Current Limit Thermal Shutdown Protection Short Circuit Protection No External Components 4 Available Packages  PART NUMBER SOT-23-3L 2 Applications      TV Board Air Conditioner Vehicle Mounted Radar Air Conditioner Charging Device VIN CIN 0.33μF IN 3 PACKAGES CJ78L Series CJ78L Series SOT-89-3L TO-92 Note: For more detailed packaging information, see the part Pin Configuration and Function and the part Mechanical Information.

The CJ78L series has a fixed output voltage version, which allows the fixed output CJ78L series to be used as an output circuit with adjustable voltage by setting two peripheral resistors. 8.2 Representative Schematic Diagram IN VT1 VT2 R4 VT11 VT10 VD3 VT3 VT4 R12 R5 VT15 VT9 VT44 R3 VD1 VT17 VT14 VT8 R1 VT5 R8 R14 R10 R13 R15 R16 R6 OUT R9 VT18 VD2 C1 R7 VT16 VT12 VT6 R17 R18 VT7 VT13 R2 www.jscj-elec.com VD5 C2 VD6 19 R11 R19 GND Rev. - 3.0 CJ78L Series 8 Detailed Description 8.3 Feature Description Input Voltage When the input voltage is lower than the rated range of the data sheet, the device will lose the regulation function of stabilizing the output voltage, that is, it is unable to maintain the output voltage within the rated range. At this time, compared with normal operation, the quiescent current of the device may exceed the rated range, and the transient response performance of the device may be seriously degraded. When the input voltage is higher than the rated range of the data sheet, the device may cause irreversible damage or failure due to exceeding the maximum rated range of electrical stress. Output Current When the circuit design is appropriate, the CJ78L series can reach the maximum load capacity of at least 100mA. According to the heat dissipation power consumption of the package and the effective connection thermal resistance with the environment, selecting the appropriate package for the circuit design can make the device emit more heat energy. Thermal Shutdown The CJ78L series has thermal shutdown protection mechanism. When the junction temperature exceeds the rated temperature range for normal operation in the data sheet, the device will enter the thermal shutdown state. At this time, the output voltage of the device will be reduced to prevent catastrophic damage to the chip due to accidental heat. When the junction temperature decreases and no longer remains too high, the device will release the thermal shutdown and output normally. To ensure reliable operation, please limit the junction temperature to the specified range of Recommended Operating Conditions in the data sheet. Applications that exceed the recommended temperature range may cause the equipment to exceed its operating specifications. Although the internal protection circuitry of the device is designed to protect against thermal overall conditions, this circuitry is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown or above the maximum recommended junction temperature reduces long-term reliability. Current Limit & Short Circuit Protection The CJ78L series has current limiting and short circuit protection mechanism. When the output current of the device is too high, the output of the device will be shut down. When the output of the device is short circuited to ground, the output of the device will also be shut down and the output current will be maintained within a certain range. www.jscj-elec.com 20 Rev. - 3.0 CJ78L Series 9 Application and Implementation 9.1 Risk Alert and Precautions The CJ78L series is designed for thermal protection, output short circuit protection and built-in current limit. However, like any IC regulator, precautions are necessary to reduce the possibility of accidental damage to the regulator. The following describes the possible causes of unit damage or failure: Electrostatic Discharge (ESD) Electrostatic discharge (ESD) is a common near-field hazard source. It comes from many sources, such as human body, mechanical equipment and electronic components themselves. ESD can cause phenomena such as high voltage and instantaneous high current in a very short time, resulting in damage or failure of the device due to electric shock. Instantaneous Electrical Surge In some applications, a short duration but high energy spike may occur in the circuit, including peak voltage and surge current. They may cause unstable operation of the regulator, accelerated aging and potential hazards, and even damage or malfunction of the regulator. These peaks are usually more likely to occur in hot-plug, switch inductance, heavy-load, and other types of circuits. Precautions for ESD and Electrical Surge In the practical application of the circuit, adopting the following suggestions can reduce the possibility of device failure due to the above reasons to a certain extent. 1. Place a TVS between the IN and GND of the voltage regulator to absorb the peak voltage that may be generated due to ESD or other reasons. As shown in Figure 9-1; 2. Place a resistor with appropriate resistance in series before the IN of the voltage regulator, which can help the voltage regulator share part of the energy in case of surge. The resistance value of the resistance should not be too large. The specific resistance value depends on the application of the circuit. Generally, the resistance value of this resistance does not exceed 20Ω. As shown in Figure 9-2. For the CJ78L05, CJ78L06, CJ78L08, CJ78L09, it is recommended that the input voltage should not exceed 16V and the peak voltage should not exceed 30V. For the CJ78L12, CJ78L15, it is recommended that the input voltage should not exceed 18V and the peak voltage should not exceed 35V. When the input voltage of the operating circuit may not meet the application conditions described above, it is recommended to adopt the circuit layout shown in Figure 9-2 in the circuit design.

Resistance is used at IN 21 Rev. - 3.0 CJ78L Series 9 Application and Implementation 9.1 Risk Alert and Precautions (continued) Large Output Capacitance The CJ78L series can obtain better transient response with the help of output capacitance. However, if the output capacitor is relatively large, the surge current generated by the charging of the output capacitor will also be large at the moment of power on of the regulator, and the large surge current passing through the regulator may damage the internal circuit. When the output capacitance is large, adopting the circuit design shown in Figure 9-2 will reduce the possibility of damage to the device due to large surge current to a certain extent. It is recommended that the selection of output capacitor should not exceed 20μF. If the selection of output capacitor exceeds 20μF, it is recommended to adopt the circuit design in Figure 9-2 to reduce the possibility of accidental failure of the device due to large surge current during power on. 9.2 Application Information Bypass Capacitance Selection A capacitance between IN and GND (CIN) is required if the regulator is located far from the power supply filter. It is recommended to use a 0.33μF capacitor for CIN, and the capacitor (CIN) should be placed as close to the device IN pin and GND pin as possible. It is recommended to use a 0.1μF capacitor between OUT and GND (COUT), and the capacitor should be placed as close as possible between OUT and GND. The output capacitance can limit the high-frequency noise and help the device obtain the best stability and transient response. The tolerance and temperature coefficient of the input and output capacitor (CIN and COUT) must be considered to ensure that the capacitor can work normally within the rated working ambient temperature and rated working conditions of the equipment. It is recommended that the output capacitor (COUT) should not exceed 20μF. When the output capacitor (COUT) exceeds 20μF, it is recommended to use the circuit layout shown in Figure 9-2. See Large Output Capacitance for more details. Design Requirements and Procedure The CJ78L series is mainly used to provide fixed output voltage regulation, the output voltage is selected based on the device variant, which is available in 5.0V, 6.0V, 8.0V, 9.0V, 12V and 15V regulator options, and it requires a very small number of equipment components. If the regulator is far from the power filter, the input capacitor CIN is required. The bypass capacitor COUT is used at the output to obtain the best stability and transient response. These capacitors must be as close to the regulator as possible. The simplest implementation of the CJ78L series is shown in Figure 9-3. www.jscj-elec.com 22 Rev. - 3.0 CJ78L Series 9 Application and Implementation 9.3 System Example VIN IN CJ78L Series GND CIN 0.33μF VOUT OUT VIN RIN IN CIN COUT 0.1μF CJ78L Series OUT GND VOUT COUT (1) Conventional Circuit (2) Resistance are used at IN Used for the normal form of circuit Used for circuits that may have large electrical surges or use large capacitors Figure 9-3. Fixed Output Regulator Note: For more details, see the part Risk Alert and Precautions. 9.4 Power Supply Recommendation The linear regulator input supply must be well regulated and kept at a voltage level to not exceed the maximum input to output voltage differential allowed by the device. The minimum dropout voltage (VDO) must be meet with extra headroom when possible to keep the output well regulated. For the best overall performance, some layout guidelines may be disregarded. Place all circuit components on the same side of the circuit board and as near as practical to the respective linear regulator pins. Traces must be kept short and wide to reduce the amount of parasitic elements in the system. The actual width and thickness of traces depends on the current carrying capability and heat dissipation required by the end system.

Relevant personnel shall comply with correct installation and use specifications to avoid ESD damage to the IC. If appropriate measures are not taken to prevent ESD damage, the hazards caused by ESD include but are not limited to degradation of integrated circuit performance or complete damage of integrated circuit. For some precision integrated circuits, a very small parameter change may cause the whole device to be inconsistent with its published specifications. Junction-to-ambient Thermal Resistance RΘJA Definition: The junction to ambient thermal resistance RΘJA is a metric of the thermal performance of the device's packages. By comparing the metric of different companies on the same product package, the thermal performance of the product can be roughly estimated in a relative sense. RΘJA is measured under the conditions specified in the corresponding specifications. If the measurement of RΘJA of two products follows different specifications and standards, or although the same specifications and standards are adopted, it is not tested in strict accordance with the specifications, then the RΘJA of two products will lose the meaning of comparison. This product follows the test specified by JEDEC in the EIA/JESD51-x series documents. RΘJA is measured in still air with TA = 25°C and installed on a 1 in 2 FR-4 board covered with 2 ounces of copper. Usage: Junction to ambient thermal resistance RΘJA is a parameter defined at the system level rather than on a single device or chip. In the test of RΘJA provided in the data sheet, most of the heat generated by the operation of the device is dissipated through the test board rather than the packaging surface of the device. In fact, the design and layout of PCB (such as chip or pad size, internal package geometry, etc.) will significantly affect RΘJA. At this time, any calculation of the junction temperature or thermal power consumption of the device by applying RΘJA in the data sheet will have a very large error, so that it does not match the real performance of the device. Therefore, RΘJA should be used as the relative comparison of product packaging thermal performance between different companies, rather than directly using RΘJA in the data sheet in the actual calculation. Reference Maximum Power Dissipation for Continuous Operation PD Ref The reference maximum power dissipation for continuous operation PD Ref is not an accurate value obtained from the actual test. It is a theoretical value obtained according to the heat dissipation capacity of packaging combined with practical application. It is used to compare the differences of heat dissipation capacity more intuitively between products of different companies. This value is only for estimation reference and cannot be used as an index of the actual performance of the device for circuit design. www.jscj-elec.com 30 Rev. - 3.0 CJ78L Series 12 Notes and Revision History 12.3 Revision History September, 2022: updated CJ78L series, rev - 3.0: Modified data sheet format: All data sheet, added headers, changed font size; Page 1, modified footer; Assembled CJ78L05, CJ78L06, CJ78L08, CJ78L09, CJ78L12 and CJ78L15 devices into the CJ78L series; Deleted obsolete CJ78L18 device from the data sheet; Added Introduction, Available Package, Applications, Pin Configuration and Marking Information, Recommended Operating Conditions, ESD Ratings, Thermal Information, Detailed Description, Application and Implementation and Notes and Revision History sections; DISCLAIMER, deleted the description of "automotive electronics". www.jscj-elec.com 31 Rev. - 3.0 DISCLAIMER IMPORTANT NOTICE, PLEASE READ CAREFULLY The information in this data sheet is intended to describe the operation and characteristics of our products.
