The input capacitor becomes more necessary when the power supply impedance is high or when the PCB trace has significant length. Moreover, the higher the capacitance of the output capacitor the more stable the output will be, even with load and line voltage variations. However, please check the actual functionality by mounting on a board for the actual application. Also, ceramic capacitors usually have different thermal and equivalent series resistance characteristics and may degrade gradually over continued use.

Refer to power dissipation curves illustrated in Figure 51 when using the IC in an environment of Ta ≥ 25 °C. Even if the ambient temperature Ta is at 25 °C, depending on the input voltage and the load current, chip junction temperature can be very high. Consider the design to be Tj ≤ Tjmax = 150 °C in all possible operating temperature range. Should by any condition the maximum junction temperature Tjmax = 150 °C rating be exceeded by the temperature increase of the chip, it may result in deterioration of the properties of the chip. The thermal impedance in this specification is based on recommended PCB and measurement condition by JEDEC standard. Verify the application and allow sufficient margins in the thermal design by the following method is used to calculate the junction temperature Tj. Tj can be calculated by either of the two following methods. 1. The following method is used to calculate the junction temperature Tj. Tj = Ta + PC × θJA Where: Tj Ta PC θJA : Junction Temperature : Ambient Temperature : Power Consumption : Thermal Impedance (Junction to Ambient) 2.

Applying positive surge to the input If the possibility exists that surges higher than absolute maximum ratings 6.5 V will be applied to the input, a Zener Diode should be placed to protect the device in between the V IN and the GND as shown in the figure 53. IN VIN D1 OUT GND CIN VOUT COUT Figure 53. Surges Higher than 6.5 V will be Applied to the Input 2. Applying negative surge to the input If the possibility exists that surges lower than absolute maximum ratings -0.3 V will be applied to the input, a Schottky Diode should be place to protect the device in between the VIN and the GND as shown in the figure 54. IN VIN D1 OUT GND CIN VOUT COUT Figure 54. Surges Lower than -0.3 V will be Applied to the Input Linear Regulators Reverse Voltage Protection A linear regulator integrated circuit (IC) requires that the input voltage is always higher than the regulated voltage. Output voltage, however, may become higher than the input voltage under specific situations or circuit configurations, and that reverse voltage and current may cause damage to the IC. A reverse polarity connection or certain inductor components can also cause a polarity reversal between the input and output pins. The following provides instructions on reversed voltage polarity protection for ICs. 1. about Input /Output Voltage Reversal In an MOS linear regulator, a parasitic element exists as a body diode in the drain-source junction portion of its power MOSFET. Reverse input/output voltage triggers the current flow from the output to the input through the body diode. The inverted current may damage or destroy the semiconductor elements of the regulator since the effect of the parasitic body diode is usually disregarded for the regulator behavior (Figure 55).

TSZ22111・15・001 21/27 TSZ02201-0G5G0A300040-1-2 30.Aug.2017 Rev.004 BUxxJA2VG-C series An effective solution to this is an external bypass diode connected in-between the input and output to prevent the reverse current flow inside the IC (see Figure 56). Note that the bypass diode must be turned on before the internal circuit of the IC. Bypass diodes in the internal circuits of MOS linear regulators must have low forward voltage V F. Some ICs are configured with current-limit thresholds to shut down high reverse current even when the output is off, allowing large leakage current from the diode to flow from the input to the output; therefore, it is necessary to choose one that has a small reverse current. Specifically, select a diode with a rated peak inverse voltage greater than the input to output voltage differential and rated forward current greater than the reverse current during use. D1 IN VIN OUT VOUT GND CIN COUT Figure 56. Bypass Diode for Reverse Current Diversion The lower forward voltage (VF) of Schottky barrier diodes cater to requirements of MOS linear regulators, however the main drawback is found in the level of their reverse current (I R), which is relatively high. So, one with a low reverse current is recommended when choosing a Schottky diode. The VR-IR characteristics versus temperatures show increases at higher temperatures. If VIN is open in a circuit as shown in the following Figure 57 with its input/output voltage being reversed, the only current that flows in the reverse current path is the bias current of the IC. Because the amperage is too low to damage or destroy the parasitic element, a reverse current bypass diode is not required for this type of circuit. ON→OFF IBIAS VIN IN VOUT OUT GND CIN COUT Figure 57. Open VIN 2. Protection against Input Reverse Voltage Accidental reverse polarity at the input connection flows a large current to the diode for electrostatic breakdown protection between the input pin of the IC and the GND pin, which may destroy the IC (see Figure 58). A Schottky barrier diode or rectifier diode connected in series with the power supply as shown in Figure 59 is the simplest solution to prevent this from happening. The solution, however, is unsuitable for a circuit powered by batteries because there is a power loss calculated as VF × IOUT, as the forward voltage VF of the diode drops in a correct connection. The lower VF of a Schottky barrier diode than that of a rectifier diode gives a slightly smaller power loss. Because diodes generate heat, care must be taken to select a diode that has enough allowance in power dissipation. A reverse connection allows a negligible reverse current to flow in the diode.

Protection against Reverse Polarity 1 TSZ02201-0G5G0A300040-1-2 30.Aug.2017 Rev.004 BUxxJA2VG-C series Figure 60 shows a circuit in which a P-channel MOSFET is connected in series with the power. The diode located in the drain-source junction portion of the MOSFET is a body diode (parasitic element). The voltage drop in a correct connection is calculated by multiplying the resistance of the MOSFET being turned on by the output current IOUT, therefore it is smaller than the voltage drop by the diode (see Figure 59) and results in less of a power loss. No current flows in a reverse connection where the MOSFET remains off. If the voltage taking account of derating is greater than the voltage rating of MOSFET gate-source junction, lower the gate-source junction voltage by connecting voltage dividing resistors as shown in Figure 61.

Protection against Output Reverse Voltage when Output Connect to an Inductor If the output load is inductive, electrical energy accumulated in the inductive load is released to the ground upon the output voltage turning off. In-between the IC output and ground pins is a diode for preventing electrostatic breakdown, in which a large current flows that could destroy the IC. To prevent this from happening, connect a Schottky barrier diode in parallel with the diode (see Figure 62). Further, if a long wire is in use for the connection between the output pin of the IC and the load, observe the waveform on an oscilloscope, since it is possible that the load becomes inductive. An additional diode is needed for a motor load that is affected by its counter electromotive force, as it produces an electrical current in a similar way.

In addition, it is impossible to predict all destructive situations such as short-circuit modes, open circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a fuse, in case the IC is operated in a special mode exceeding the absolute maximum ratings. 2) GND Potential GND potential must be the lowest potential of all pins of the IC at all operating conditions. Ensure that no pins are at a voltage below the ground pin at any time, even during transient condition. 3) Setting of Heat Carry out the heat design that have adequate margin considering Pd of actual working states. 4) Pin Short and Mistake Fitting When mounting the IC on the PCB, pay attention to the orientation of the IC. If there is mistake in the placement, the IC may be burned up. 5) Mutual Impedance Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance as small as possible. Use a capacitor to keep ripple to a minimum. 6) STBY Pin Voltage To enable standby mode for all channels, set the STBY pin to 0.5 V or less, and for normal operation, to 1.1 V or more. Setting STBY to a voltage between 0.5 and 1.1 V may cause malfunction and should be avoided. Keep transition time between high and low (or vice versa) to a minimum. Additionally, if STBY is shorted to VIN, the IC will switch to standby mode and disable the output discharge circuit, causing a temporary voltage to remain on the output pin. If the IC is switched on again while this voltage is present, overshoot may occur on the output. Therefore, in applications where these pins are shorted, the output should always be completely discharged before turning the IC on. 7) Over Current Protection Circuit Over current and short circuit protection is built-in at the output, and IC destruction is prevented at the time of load short circuit. These protection circuits are effective in the destructive prevention by sudden accidents, please avoid applications to where the over current protection circuit operates continuously. 8) Thermal Shutdown This IC has Thermal Shutdown Circuit (TSD Circuit). When the temperature of IC Chip is higher than 180°C(typ), the output is turned off by TSD Circuit. TSD Circuit is only designed for protecting IC from thermal over load. Therefore it is not recommended that you design application where TSD will work in normal condition. 9) Output capacitor To prevent oscillation at output, it is recommended that the IC be operated at the stable region shown in Figure 50. It operates at the capacitance of more than 0.47μF. As capacitance is larger, stability becomes more stable and characteristic of output load fluctuation is also improved. www.rohm.com © 2014 ROHM Co., Ltd. All rights reserved.
