SSP1117-1.2V

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

SSP1117-1.2V from Shanghai Siproin Microelectronics, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the regulator. On the fixed-output SSP1117-1.2V this pin is the device ground return; on the -ADJ version this same pin becomes the ADJ feedback input.
2 VOUT power_out Regulated 1.2V output (typ. 1.176V-1.224V). Sources up to 1A. Requires a 10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply. Recommended operating range up to 20V, absolute maximum 30V. For the 1.2V output variant, minimum Vin is ~2.7V (1.3V dropout at 1A). A 10uF tantalum bypass capacitor is recommended.
