LM78L05MK

HGSEMI · Linear Voltage Regulators (LDO) · SOT-89

LM78L05MK from HGSEMI, 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 VOUT power_out Regulated 5 V output (4.8 to 5.2 V at TJ = 25°C), delivering up to 100 mA output current.
2 GND power_in Ground reference pin for input and output, which is also connected to the package tab shown in the connection diagram.
3 VIN power_in Unregulated DC input with a maximum rating of 30 V for the 5 V version (VO = 3.3 to 10 V) and a recommended 7 to 20 V for regulation.

CAD (KiCad official)

  • Symbol: LM78L05MK
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89 (KiCad packages3D, STEP)
  • 3D model files: lm78l05mk-etched.step / lm78l05mk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm78l05mk.step / lm78l05mk.glb are the bare package body.
