MIC5501-3.0YM5-TR

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

MIC5501-3.0YM5-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 VIN power_in Supply input; the datasheet operating range is 2.5 V to 5.5 V, with an absolute maximum of -0.3 V to +6 V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Active-high enable: high turns the output on and low turns it off, with logic-low at or below 0.2 V and logic-high at or above 1.2 V; the MIC5501 must not be left floating, while the internal pull-down on this pin is present only on MIC5503/MIC5504.
4 NC unconnected No connection; the pin is not internally connected.
5 VOUT power_out Regulated output voltage (1.0 V to 3.3 V fixed options); the internal 25 Ω output discharge applies only to the MIC5502 and MIC5504, not to this MIC5501 part.
