TLE4270-2D

Infineon Technologies · Linear Voltage Regulators (LDO) · TO-252-4

TLE4270-2D from Infineon Technologies, in a TO-252-4. 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 I power_in Input supply (6 V to 42 V functional range); block to ground directly at the IC with a ceramic capacitor.
2 RO output Reset output; open collector output connected to the 5-V output via an integrated 30 kΩ resistor.
3 GND power_in Ground; internally connected to heatsink.
4 D passive Reset delay; connect a capacitor to ground for delay time adjustment.
5 Q power_out 5-V output; block to ground with 22 µF capacitor, ESR < 3 Ω.

CAD (KiCad official)

  • Symbol: TLE4270-2D
  • Footprint: Package_TO_SOT_SMD:TO-252-4
  • 3D model: TO-252-4 (KiCad packages3D, STEP)
  • 3D model files: tle4270-2d-etched.step / tle4270-2d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tle4270-2d.step / tle4270-2d.glb are the bare package body.
