Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223
SSP1117-2.5V 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 | GND | power_in | Ground pin on the fixed 2.5V version (labelled ADJ/GND; it is the ADJ pin only on the adjustable version), returned to the input and output capacitor grounds. |
| 2 | VOUT | power_out | Regulated 2.5V output (2.45V to 2.55V for 0 to 1A load), with a recommended 10uF tantalum output capacitor for stability. |
| 3 | VIN | power_in | Input supply, recommended maximum 20V (absolute maximum 30V), with a recommended 10uF tantalum bypass capacitor. |
