MIC5219-3.3YM5-MS

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

MIC5219-3.3YM5-MS from MSKSEMI, 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 VIN power_in Input supply voltage for the regulator, specified at 2V to 24V (VIN absolute maximum is -0.3V to 24V).
2 GND power_in Ground pin; the input and output capacitor ground connections should return to this pin through a wide, short copper trace.
3 EN input Enable control input for the regulator.
4 NC unconnected No internal connection.
5 VOUT power_out Regulator output; the output capacitor must have at least 1mΩ ESR and an effective capacitance between 1µF and 22µF.
