MCP120T-450I 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 that asserts whenever VDD is below the trip point and is held for 350 ms (typ) after VDD rises above it; the MCP130 adds an internal 5 kΩ pull-up, while the MCP120 needs an external pull-up. |
| 2 | VDD | power_in | Supply voltage and monitored input, operating range 1.0 V to 5.5V (absolute maximum 7.0 V), with RESET asserted whenever VDD is below the trip-point voltage. |
| 3 | VSS | power_in | Ground reference for the device; inputs and outputs are rated -0.6 V to VDD + 1.0 V with respect to VSS. |
