LD1117V33

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220

LD1117V33 from STMicroelectronics, in a TO-220. 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 pin of the regulator; for the fixed 3.3 V version the output capacitor and input capacitor return here.
2 VOUT power_out Regulated 3.3 V output delivering up to 800 mA, requiring a minimum 10 µF output capacitor for stability; the TAB is connected to this pin.
3 VIN power_in Unregulated input voltage pin with a maximum operating input voltage of 15 V (absolute maximum 15 V, or 18 V when IOUT is below 20 mA).

  • Symbol: LD1117V33
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: ld1117v33-etched.step / ld1117v33-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ld1117v33.step / ld1117v33.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (44 pp, sha256 1b80923ec6ca9161, retrieved 2026-11-05, tier: manufacturer)
  • 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).
