SSP1117-3.3V

Siproin's datasheet does not state the tab connection; this land follows the 1117-family convention (tab = Vout). Check before use.

Shanghai · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

SSP1117-3.3V from Shanghai, in a SOT-223-3. 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 ADJ/GND input Ground return for the regulator. On the fixed-output SSP1117-3.3V this pin is the device ground reference; on the ADJ variant the same pin becomes the ADJ feedback node.
2 VOUT power_out Regulated 3.3V output. Sources up to 1A load current. Requires a 10uF tantalum output capacitor for stability.
3 VIN power_in Unregulated input supply. Recommended maximum 20V, absolute max 30V. For the 3.3V output, minimum operating Vin is 4.8V with a 10uF tantalum bypass capacitor recommended.
