AMS1117KTP-3.3RG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

AMS1117KTP-3.3RG from HANSCHIP semiconductor, in a TO-252. 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 3.3V version; the datasheet labels it GND/ADJ, and the ADJ function applies only to the adjustable version.
2 VOUT power_out Regulated output voltage, specified at 3.3 V with a 3.250 V to 3.365 V range at 10 mA load, and rated for output current up to 800 mA.
3 VIN power_in Input operating voltage with an absolute maximum of 15 V and a recommended input voltage of up to 12 V.
