78L05T

Foshan Blue Rocket Elec · Linear Voltage Regulators (LDO) · SOT-89-3

78L05T from Foshan Blue Rocket Elec, 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 OUT power_out Regulated output, nominally 5.0 V, held between 4.75 V and 5.25 V for IO = 1 mA to 40 mA with VI = 7 V to 20 V, with output current rated up to 100 mA.
2 GND power_in Ground pin; the datasheet states only its pin assignment and gives no separate electrical limit for it.
3 IN power_in Unregulated input supply with a maximum input voltage of 30 V, and regulation is specified for VI = 7 V to 20 V.

CAD (KiCad official)

  • Symbol: 78L05T
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: 78l05t-etched.step / 78l05t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 78l05t.step / 78l05t.glb are the bare package body.
