KF80BDT-TR

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

KF80BDT-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 Regulator input voltage, operating up to 20 V (absolute maximum -0.5 to 20 V), with a 0.1 µF input capacitor used in the datasheet test circuits.
2 GND power_in Ground, connected internally to the mounting tab (the tab is labelled GND in the DPAK drawing).
3 OUTPUT power_out Regulated 8 V output (7.84 to 8.16 V at 25 °C, 50 mA), up to 500 mA with internal current limit around 1 A, needing a 2.2 to 10 µF output capacitor with ESR 0.1 to 10 Ω.

CAD (KiCad official)

  • Symbol: KF80BDT-TR
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: DPAK (KiCad packages3D, STEP)
  • 3D model files: kf80bdt-tr-etched.step / kf80bdt-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kf80bdt-tr.step / kf80bdt-tr.glb are the bare package body.
