MIC803-30D4VM3-TR from Microchip Tech, in a SOT-23. 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 | GND | power_in | Ground. |
| 2 | /RESET | output | Open-drain active-low reset output that goes low if VCC falls below the reset threshold (VTH) and stays asserted for one timeout period after VCC exceeds VTH; needs a pull-up resistor limited to 5.5V and remains valid with VCC as low as 1.0V. |
| 3 | VCC | power_in | Power supply input and monitored voltage, operating range 1.0V to 5.5V (absolute maximum 6.0V). |
