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

MIC5219-5.0YM5-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 rating is +2.5V to +12V, and the absolute maximum supply input voltage is -20V to +20V.
2 GND power_in Ground pin; ground pin current is the regulator quiescent current plus pass transistor base current.
3 EN input CMOS-compatible enable input where logic high (VEN ≥ 2.0V) enables the regulator and logic low or open (VEN ≤ 0.4V) shuts it down, with an operating rating of 0V to VIN.
4 BYP passive Reference bypass for the fixed-voltage version; an external 470pF capacitor to GND reduces output noise and the pin may be left open, though higher CBYP slows start-up.
5 OUT power_out Regulator output that requires an output capacitor to GND (1µF minimum without CBYP, 2.2µF minimum with 470pF CBYP) to prevent oscillation.
