LM78L15TA

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3

LM78L15TA from HTC Korea TAEJIN Tech, in a TO-92-3. 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 15 V output rated for up to 100 mA of output current, held within 14.25 V to 15.75 V over -30 °C to 125 °C at 1 mA ≤ Io ≤ 70 mA.
2 GND power_in Ground reference pin shared by the input and output of the regulator.
3 VIN power_in Unregulated input for the LM78L15, with a recommended range of 17.5 V to 30 V and an absolute maximum of 35 V for the LM78L12 to LM78L18 group.
