AMS1117-5.0V

MSKSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

AMS1117-5.0V from MSKSEMI, in a SOT-89. 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 VSS/ADJ power_in VSS/ADJ pin, the ground/adjust connection; on the adjustable version it sets the output voltage through the external resistor divider, with adjust pin current specified at 55 to 120 µA.
2 VOUT power_out Output voltage pin delivering the regulated output, 5.0V for this fixed version, with load current up to 1A.
3 VIN power_in Input voltage pin; the datasheet gives an operating input range up to 15V and an absolute maximum input voltage of 18V.
