MIC5205-3.0YM5-TR

Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

MIC5205-3.0YM5-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; the Operating Ratings specify VIN from +2.5V to +16V, with absolute maximum input voltage of -20V to +20V.
2 GND power_in Ground pin for the regulator and for the external output, bypass and input capacitors.
3 EN input Enable/shutdown CMOS-compatible input: logic high (above 2V) enables the regulator, while logic low (0.4V or below, 0.18V for full shutdown) or open shuts it down.
4 BYP passive Reference bypass: a 470pF capacitor from BYP to GND reduces output noise, and the pin may be left open.
5 OUT power_out Regulator output; it requires an output capacitor to GND to prevent oscillation, at least 2.2µF when a 470pF BYP capacitor is used and 1.0µF minimum without it.
