SSP1117-5.0V
Public Made by Adomby adom
Shanghai Siproin Microelectronics Voltage Regulators - Linear, Low Drop Out (LDO) Regulators, SOT-223. Pinout settled in review by an AI reviewer against the manufacturer's datasheet, KiCad symbol/footprint/3D.
SSP1117-5.0V
Siproin's datasheet does not state the tab connection; this land follows the 1117-family convention (tab = Vout). Check before use.

SSP1117-5.0V from Shanghai Siproin Microelectronics, in a SOT-223. 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 reference for the regulator. On fixed-voltage versions (including SSP1117-5.0V) pin 1 is the GND return; on the ADJ variant this same pin serves as the ADJ feedback node. |
| 2 | VOUT | power_out | Regulated 5.0V output (typ, ±2%). Delivers up to 1A load current. Requires a ~10uF tantalum output capacitor for stability. |
| 3 | VIN | power_in | Unregulated input supply. Recommended max 20V (absolute max 30V). For 5.0V output, Vin must exceed Vout by the dropout voltage (~1.3V at 1A). Recommended 10uF tantalum bypass capacitor to GND. |
