AMS1117-5.0RG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

AMS1117-5.0RG from HANSCHIP semiconductor, in a SOT-223. 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/ADJ power_in Ground for the fixed-voltage versions and the adjust pin for the adjustable version (datasheet lists it as 地/ADJ).
2 VOUT power_out Regulated output voltage; the adjustable version requires at least a 22 µF tantalum output capacitor for stability, while fixed versions may use smaller capacitors.
3 VIN power_in Input supply voltage; the absolute maximum input is 15 V and the recommended input voltage is 12 V.
