78L05ML-T92-B

UTC(Unisonic Tech) · Linear Voltage Regulators (LDO) · TO-92-2.54mm

78L05ML-T92-B from UTC(Unisonic Tech), in a TO-92-2.54mm. 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 OUTPUT power_out Regulated output voltage of the 78L05 (5 V fixed), rated for output current up to 200 mA per the datasheet.
2 GND power_in Ground (common) reference pin for the regulator.
3 INPUT power_in Unregulated input voltage to the regulator; absolute maximum input voltage is 30 V for VOUT = 5 to 9 V.

  • Symbol: 78L05ML-T92-B
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92-2.54mm (KiCad packages3D, STEP)
  • 3D model files: 78l05ml-t92-b-etched.step / 78l05ml-t92-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78l05ml-t92-b.step / 78l05ml-t92-b.glb are the bare package body.
