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

LM78L24F 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 24V output of the LM78L24 (nominal 24V); the datasheet rates the output current up to 100mA.
2 GND power_in Ground reference pin for the regulator.
3 VIN power_in Unregulated input voltage; for the LM78L24 the absolute maximum input is 40V and the recommended input range is 26.5V to 39V.
