SL9193M25SA from Slkor SLKORMICRO Elec, in a SOT-23. 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 reference pin; the input and output capacitor ground connections must return to this pin using as wide and short a copper trace as practical. |
| 2 | VOUT | power_out | Regulated output voltage (2.5 V for the SL9193M25 variant); absolute maximum voltage is -0.3 V to VIN+0.3 V and a minimum 1 µF ceramic output capacitor (X7R or X5R) must be placed close to VOUT and GND for stability. |
| 3 | VIN | power_in | Power input voltage; operating supply range is 2 V to 6.5 V with an absolute maximum input rating of -0.3 V to 7 V, and a 1 µF ceramic decoupling capacitor should be placed as close as possible to VIN and GND. |
