# MIC5365-1.8YC5-TR

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

MIC5365-1.8YC5-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; the datasheet specifies an input voltage range of 2.5V to 5.5V (absolute maximum 6V). |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Active-high enable input (high = ON, low = OFF), which must not be left floating and is specified with a 0V to VIN enable voltage range. |
| 4 | NC | unconnected | No connect; not internally connected. |
| 5 | VOUT | power_out | Regulated output voltage; the 1.8V variant (MIC5365-1.8YC5) provides 1.8V nominal with ±2% initial accuracy. |
