LM78L15F

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

LM78L15F from HTC Korea TAEJIN Tech, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated 15V output of the LM78L15, delivering up to 100mA of output current, with a 0.1uF output bypass capacitor recommended close to the regulator.
2 GND power_in Ground reference pin for the regulator.
3 VIN power_in Unregulated input voltage; the LM78L15 recommended input range is 17.5V to 30V, with an absolute maximum of 35V, and a bypass capacitor is recommended close to the regulator.
