# MIC5365-3.3YC5-TR

**Microchip Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

MIC5365-3.3YC5-TR from Microchip Tech, in a SC-70-5. 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 for the regulator; the datasheet gives an operating supply range of 2.5V to 5.5V, with an absolute maximum of 6V. |
| 2 | GND | power_in | Ground pin; the ground pin current is the regulator quiescent current, typically 29µA at 0mA load. |
| 3 | EN | input | Active-high enable input: high turns the output on and low turns it off, with logic low at 0.2V max and logic high at 1.2V min, and it must not be left floating. |
| 4 | NC | unconnected | No connect; not internally connected. |
| 5 | VOUT | power_out | Regulated output voltage (3.3V for this version), guaranteed up to 150mA output current and stable with a 1µF ceramic output capacitor. |
