AMS1117DCY-1.5RG

HANSCHIP semiconductor · Linear Voltage Regulators (LDO) · SOT-223-3L

AMS1117DCY-1.5RG from HANSCHIP semiconductor, in a SOT-223-3L. 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 pin for the fixed-output AMS1117-1.5 variant; on the adjustable version this pin is the ADJ terminal instead (datasheet pinout table lists it as GND/ADJ, I/O '--/O').
2 VOUT output Regulated output voltage; for the AMS1117-1.5 it is specified at 1.470 V min, 1.500 V typ, 1.530 V max with IOUT=10 mA, VIN=3.5 V, TJ=25°C, and the output must be loaded for stability (adjustable version requires at least 22 µF tantalum at the output).
3 VIN power_in Input operating voltage; recommended maximum is 12 V and the absolute maximum input voltage is 15 V.
