MIC2920A-5.0WS-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 | Unregulated input supply, operating range 2V to 26V, withstands -20V reverse battery and 60V positive transients of limited duration (<100ms, duty cycle ≤1%). |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | OUT | power_out | Regulated 5.0V output, which requires a 10µF (or greater) output capacitor to ground for stability. |
