MIC5209-3.3YS-TR

Microchip Tech · Linear Voltage Regulators (LDO) · SOT-223

MIC5209-3.3YS-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 range is +2.5V to +16V and the absolute maximum supply voltage is -20V to +20V.
2 GND power_in Ground; SOT-223 pin 2 and TAB are internally connected.
3 OUT power_out Regulator output; a 1 µF minimum output capacitor is required for basic fixed-voltage applications.
