78L08K

Shikues · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

78L08K from Shikues, in a SOT-89. 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 OUT power_out Regulated output of the 78L08K, rated for a maximum output current of 100 mA with an 8 V nominal output (7.6 V to 8.4 V over 10 V to 23 V input and 1 mA to 40 mA load at 25 °C to 125 °C).
2 GND power_in Ground reference pin for the regulator; the datasheet gives no separate limit for this pin.
3 IN power_in Unregulated input to the regulator, with an absolute maximum input voltage of 30 V for the 4.4 V to 10 V output variants (the 78L08K falls in this group).

CAD (KiCad official)

  • Symbol: 78L08K
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: 78l08k-etched.step / 78l08k-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78l08k.step / 78l08k.glb are the bare package body.
