MIC5203-3.3YM5-TR

Microchip Tech · Linear Voltage Regulators (LDO) · SOT-23-5

MIC5203-3.3YM5-TR from Microchip Tech, in a SOT-23-5. 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; operating input voltage range is 2.5V to 16V.
2 GND power_in Ground.
3 EN input Enable input, TTL/CMOS compatible: logic high (above 2.0V) = enabled; logic low (below 0.6V) or open = shutdown.
4 NC unconnected Not internally connected.
5 OUT power_out Regulator output; typically requires only 0.47µF of output capacitance for stability.
