MIC39100MP-3.3

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

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.
