AT73HL50SC

Agertech · Linear Voltage Regulators (LDO) · SOT-23-3L

AT73HL50SC from Agertech, in a SOT-23-3L. 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 GND power_in Ground reference for the regulator.
2 VOUT power_out Regulated output (fixed 1.8V to 5.7V, 250mA at VIN=12V and VOUT=5V, absolute maximum -0.3 to 6.5V) with a recommended 10uF output capacitor.
3 VIN power_in Power input with a recommended operating range of 4.75V to 40V (absolute maximum -0.3 to 45V) and a recommended 10uF input capacitor.

CAD (KiCad official)

  • Symbol: AT73HL50SC
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: at73hl50sc-etched.step / at73hl50sc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at73hl50sc.step / at73hl50sc.glb are the bare package body.

Provenance

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

  • Datasheet: Agertech datasheet (8 pp, sha256 bc766c8ff0d1cdc8, retrieved 2026-11-02, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
