SSP1117-1.8V

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

SSP1117-1.8V 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 fixed-voltage versions (including the 1.8V variant), pin 1 is the ground return. On the adjustable version this same pin becomes the ADJ feedback input.
2 VOUT power_out Regulated 1.8V output. Supplies up to 1.0A load current. Requires a 10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply, up to 20V maximum. A 10uF tantalum bypass capacitor is recommended from VIN to GND.
