LF18ABDT-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DPAK

LF18ABDT-TR from STMicroelectronics, in a DPAK. 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 INPUT power_in DC supply input; operating range 3 to 16 V (IO = 500 mA); absolute maximum −0.5 to 40 V (regulator enters shutdown for 18 V < VI < 40 V).
2 GND power_in Ground reference; electrically shorted to the exposed heatsink TAB; quiescent current 0.5 mA typ / 1 mA max (ON mode, IO = 0 mA).
3 OUTPUT power_out Regulated 1.8 V output (±1% at 25 °C: 1.782 V min, 1.818 V max at IO = 50 mA, VI = 3.3 V); maximum continuous output current 500 mA; dropout voltage 0.7 V at IO = 200 mA.

CAD (KiCad official)

  • Symbol: LF18ABDT-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: lf18abdt-tr-etched.step / lf18abdt-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf18abdt-tr.step / lf18abdt-tr.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (53 pp, sha256 307003c143a6294f, retrieved 2026-09-27, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.2, primary claude-sonnet-4-6 (text+vision), consensus claude-opus-4-7 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
