MIC39100-2.5WS-TR from Microchip Tech, 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 | IN | power_in | Supply input; the operating supply voltage range is +2.25V to +16V, and the absolute maximum supply voltage is -20V to +20V. |
| 2 | GND | power_in | Ground; this pin is connected to the TAB, which is also ground. |
| 3 | OUT | power_out | Regulator output; when the output capacitor is 10 µF or greater, its ESR should be less than 2Ω for stability and transient response. |
