LD1117V50C

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

LD1117V50C 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 (labelled ADJ/GND in the pin drawing; ground on the fixed 5.0 V version, adjustment pin on the adjustable version).
2 VOUT power_out Regulated 5 V output (4.9 to 5.1 V over 0 to 800 mA) with a minimum 10 µF output capacitor for stability; the TAB is also connected to VOUT.
3 VIN power_in Input supply pin; operating input voltage is 15 V maximum (absolute maximum 15 V, or 18 V when IOUT is below 20 mA).
