MIC5365-3.3YD5-TR

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

MIC5365-3.3YD5-TR from Microchip Tech, in a TSOT-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; operating supply range is 2.5V to 5.5V, with an absolute maximum of 6V.
2 GND power_in Ground pin for the regulator.
3 EN input Active-high enable input: high turns the output on and low turns it off (zero off-mode current); operating range is 0V to VIN and it must not be left floating.
4 NC unconnected No connect; not internally connected.
5 VOUT power_out Regulated output voltage (3.3V nominal for this -3.3 version), with 1µF ceramic output capacitor required for stability.
