# MCP130T-270I

**Microchip Tech** · Supervisor And Reset ICs · SOT-23-3

MCP130T-270I from Microchip Tech, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RST | output | Active-low open-drain reset output; internal 5kΩ pull-up resistor on MCP130 keeps output high when VDD > VTRIP + 50mV hysteresis. |
| 2 | VSS | power_in | Ground/common reference voltage. |
| 3 | VDD | power_in | Supply voltage input; operating range 1.0V to 5.5V; monitored against 2.55-2.70V trip point (MCP130T-270I). |
