MCP120T-475I 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 | RST | output | Active-low open-drain RESET output, asserted whenever VDD is below the trip point (4.50V to 4.75V for the -475 option) and held for 350 ms typical (150 to 700 ms) after VDD rises above it; MCP120 has no internal pull-up. |
| 2 | VDD | power_in | Supply voltage and monitored input, operating range 1.0V to 5.5V with an absolute maximum of 7.0V. |
| 3 | VSS | power_in | Ground reference for the device; all inputs and outputs are rated -0.6V to VDD+1.0V with respect to VSS. |
