MIC39100MP-3.3 from HGSEMI, 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; recommended operating range is +2.25V to +16V (absolute maximum ±20V), with a 1µF or greater input capacitor recommended if far from bulk supply capacitance. |
| 2 | GND | power_in | Ground pin, connected internally to the TAB. |
| 3 | OUT | power_out | Regulator output (fixed 3.3V for this variant), delivering 1A minimum guaranteed and needing an output capacitor (10µF or greater with ESR below 2Ω) for stability. |
