STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2(DPAK)

LD1117DT25CTR from STMicroelectronics, in a TO-252-2(DPAK). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference pin for the fixed-voltage regulator; a 120 Ω resistor between GND and OUT is used in the electrical-characteristics test circuit to set the internal reference condition.
2 VOUT power_out Regulated output voltage pin (fixed 2.5 V, ±1% at 25°C), capable of delivering up to 800 mA output current; requires a minimum 10 µF output capacitor for stability.
3 VIN power_in Unregulated DC input voltage pin; operating input voltage up to 15 V (absolute maximum 18 V when IOUT < 20 mA).
