MIC803-26D3VM3-TR from Microchip Tech, in a SOT-23-3. 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 reference pin for the device. |
| 2 | /RESET | output | /RESET goes low if VCC falls below the reset threshold (VTH) and remains asserted for one timeout period after VCC exceeds VTH; it is an open-drain output that needs an external pull-up resistor and stays valid with VCC as low as 1.0V. |
| 3 | VCC | power_in | Power supply input and monitored voltage, with an operating voltage range of 1.0V to 5.5V. |
