KF25BD-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SO-8

KF25BD-TR from STMicroelectronics, in a SO-8. 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 2.5 V output (KF25B) delivering up to 500 mA, requiring a 2.2 µF output capacitor (ESR 0.1 to 10 Ω) for stability.
2 GND power_in Ground pin, connected to the other GND pins.
3 GND power_in Ground pin, connected to the other GND pins.
4 NC unconnected No internal connection.
5 INHIBIT input TTL-compatible logic shutdown control input, with low level 0.8 V max and high level 2 V min (Ta -40 to 125 °C), that puts the regulator in OFF mode.
6 GND power_in Ground pin, connected to the other GND pins.
7 GND power_in Ground pin, connected to the other GND pins.
8 VIN power_in Unregulated DC input voltage, absolute maximum -0.5 to 20 V, with 20 V maximum operating input at 500 mA.

CAD (KiCad official)

  • Symbol: KF25BD-TR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: kf25bd-tr-etched.step / kf25bd-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); kf25bd-tr.step / kf25bd-tr.glb are the bare package body.
