MG78L05T3

Megain · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

MG78L05T3 from Megain, in a SOT-23-3. 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 output voltage pin, nominally 5 V, rated for up to 120 mA when the regulator has adequate heat sinking.
2 VIN power_in Input voltage pin; the recommended input range is 7 V to 30 V, and the absolute maximum rating is -0.3 V to +35 V.
3 GND power_in Ground pin, the common return for the input and output of the regulator.

CAD (KiCad official)

  • Symbol: MG78L05T3
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: mg78l05t3-etched.step / mg78l05t3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mg78l05t3.step / mg78l05t3.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Megain datasheet (8 pp, sha256 6d046aa351bd5463, retrieved 2026-10-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
