The LM39300/1 offers extremely low dropout (typically 400mV at 3.0A) and low ground current (typically 36mA at 3.0A). The LM39300/1/2 is ideal for PC add-in cards that need to convert from standard 5V or 3.3V down to new, lower core voltages. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the LM39300/1/2 to pro-vide 2.5V from a supply as low as 3V. The LM39300/1/2 also has fast transient response for heavy switching applications.The device requires only 47F of output capacitance to maintain stability and achieve fast transient responseThe LM39300/1 is fully protected with over current limiting,thermal shutdown, reversed-battery protection, reversed-leakage protection, and reversed-lead insertion. The LM39301 offers a TTL-logic compatible enable pin and an error flag that indicates under voltage and over current conditions. Offered in fixed voltages, the LM39300/1/2 comesin the TO-220 and TO-263 packages and is an ideal upgrade to older, NPN-based linear voltage regulators.

Its 500mV dropout voltage at full load makes it especially valuable in battery-powered systems and as a high-efficiency noise filter in post-regulator applications. Unlike older NPN-pass transistor designs, where the mini-mum dropout voltage is limited by the base-to-emitter voltage drop and collector-toemitter saturation voltage, dropout per-formance of the PNP output of these devices is limited only by the low V CE saturation voltage.A trade-off for the low dropout voltage is a varying base drive requirement. The LM39300/1/2 regulator is fully protected from damage due to fault conditions. Current limiting is provided. This limiting is linear output current during overload conditions is constant. Thermal shutdown disables the device when the die temperature exceeds the maximum safe operating tem-perature. Transient protection allows device (and load) survival even when the input voltage spikes above and below nominal. The output structure of these regulators allows voltages in excess of the desired output voltage to be applied without reverse current flow. Thermal Design Linear regulators are simple to use. The most complicated design parameters to consider are thermal characteristics.Thermal design requires four application-specific param-eters:  Maximum ambient temperature (TA)  Output Current (IOUT)  Output Voltage (VOUT)  Input Voltage (VIN)  Ground Current (IGND) Calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet,where the ground current is taken from the data sheet. PD = (VIN – VOUT) IOUT + VIN·IGND The heat sink thermal resistance is determined by: θSA=(TJMAX-TA)/PD -(θJC+θCS) where TJ (max) 125°C and θCS is between 0°C and 2°C/W. The heat sink may be significantly reduced in applications where the minimum input voltage is known and is large compared with the dropout voltage. Use a series input resistor to drop excessive voltage and distribute the heat between this resistor and the regulator. The low dropout properties of Taejin regulators allow signifi-cant reductions in regulator power dissipation and the asso-ciated heat sink without compromising performance. When this technique is employed, a capacitor of at least 1.0F is needed directly between the input and regulator ground.Refer to Application Note 9 for further details and examples on thermal design and heat sink specification. http://www.hgsemi.com.cn 10 / 16 2018 AUG LM39300/39301/39302 Output Capacitor The LM39300/1/2 requires an output capacitor to maintain stability and improve transient response. Proper capacitor selection is important to ensure proper operation. The LM39300/1/2 output capacitor selection is dependent upon the ESR (equivalent series resistance) of the output capacitor to maintain stability. When the output capacitor is 47F or greater, the output capacitor should have less than 1 of ESR. This will improve transient response as well as promote stability. Ultralow ESR capacitors, such as ceramic chip capacitors may promote instability. These very low ESR levels may cause an oscillation and/or under damped transient response. A low-ESR solid tantalum capacitor works extremely well and provides good transient response and stability over temperature. Aluminum electrolytics can also be used, as long as the ESR of the capacitor is < 1.The value of the output capacitor can be increased without limit. Higher capacitance values help to improve transient response and ripple rejection and reduce output noise. Input Capacitor An input capacitor of 1F or greater is recommended when the device is more than 4 inches away from the bulk ac supply capacitance, or when the supply is a battery. Small, surface-mount, ceramic chip capacitors can be used for the bypassing. Larger values will help to improve ripple rejection by bypassing the input to the regulator, further improving the integrity of the output voltage.Transient Response and 3.3V. Fig 1. Capacitor Requirements Minimum Load Curren The LM39300/1/2 regulator is specified between finite loads. If the output current is too small, leakage currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. http://www.hgsemi.com.cn 11 / 16 2018 AUG LM39300/39301/39302 Transient Response and 3.3V to 2.5V Conversion The LM39300/1/2 has excellent transient response to varia-tions in input voltage and load current. The device has been designed to respond quickly to load current variations and input voltage variations. Large output capacitors are not required to obtain this performance. A standard 47F output capacitor, preferably tantalum, is all that is required. Larger values help to improve performance even further.By virtue of its low-dropout voltage, this device does not saturate into dropout as readily as similar NPN-based de-signs. When converting from 3.3V to 2.5V, the NPN-based regulators are already operating in dropout, with typical dropout requirements of 1.2V or greater. To convert down to 2.5V without operating in dropout, NPN-based regulators require an input voltage of 3.7V at the very least. The LM39300/1/2 regulator will provide excellent performance with an input as low as 3.0V.This gives the PNP-based regulators a distinct advantage over older, NPN-based linear regulators. Error Flag The LM39301 version features an error flag circuit which monitors the output voltage and signals an error condition when the voltage drops 5% below the nominal output voltage. The error flag is an open-collector output that can sink 10mA during a fault condition.Low output voltage can be caused by a number of problems, including an overcurrent fault (device in current limit) or low input voltage. The flag is inoperative during overtemperature shutdown. Enable Input The LM39301 version features an enable input for on/off control of the device. Its shutdown state draws “zero” current (only micro amperes of leakage). The enable input is TTL/ CMOS compatible for simple logic interface, but can be connected to up to 20V. When enabled, it draws approximately 15A. Adjustable Regulator Design The LM39302 allows programming the output voltage any-where between 1.25V and the 16V maximum operating rating of the family. Two resistors are used. Resistors can be quite large, up to 1MΩ, because of the very high input impedance and low bias current of the sense comparator: The resistor values are calculated by : R1=R2(Vout/1.250- 1) Where VO is the desired output voltage. Figure 1 shows component definition. Applications with widely varying load currents may scale the resistors to draw the minimum load current required for proper operation (see below). http://www.hgsemi.com.cn 12 / 16 2018 AUG LM39300/39301/39302 Physical Dimensions TO-263-3 a Dimensions In Millimeters(TO-263-3 ) A A1 B C D D1 E F G a Min： 4.45 1.22 10 1.89 13.7 8.38 0 8.332 7.70 0.71 Max： 4.62 1.32 10.4 2.19 14.6 8.89 0.305 8.552 8.10 0.97 Symbol： b 2.54BSC TO-220-3 Dimensions In Millimeters(TO-220-3) A A1 B D D1 D2 F G a d b q Min： 4.45 1.22 10 28.2 22.22 8.50 8.30 12.55 0.71 0.33 2.54 3.80 Max： 4.62 1.32 10.4 28.9 22.62 9.10 8.55 12.75 0.97 0.42 BSC TYP Symbol： http://www.hgsemi.com.cn 13 / 16 2018 AUG LM39300/39301/39302 Physical Dimensions TO-263-5 D C C1 B a 0,25 b Dimensions In Millimeters(TO-263-5) A A1 B C C1 D E a Min： 4.45 1.22 10 13.7 8.40 1.90 0 0.71 Max： 4.62 1.32 10.4 14.6 8.90 2.10 0.20 0.97 Symbol： b 1.70BSC TO-220-5 Dimensions In Millimeters(TO-220-5) A A1 B D D1 D2 a d Min： 4.52 1.25 10 28.2 22.4 8.69 0.71 0.33 Max： 4.62 1.29 10.3 28.9 22.6 8.79 0.97 0.42 Symbol： http://www.hgsemi.com.cn 14 / 16 b 1.70BSC 2018 AUG LM39300/39301/39302 Revision History DATE REVISION 2018-8-12 New 2023-7-27 Modify the package dimension diagram TO-220-5、Update encapsulation type、 Update Lead Temperature、Update PIN Configuration http://www.hgsemi.com.cn PAGE 1-16 15 / 16 14、1、4、3 2018 AUG LM39300/39301/39302 IMPORTANT STATEMENT: Huaguan Semiconductor reserves the right to change its products and services without notice.
