**Microchip Tech** · Temperature Sensors · TO-92

MCP9701A-E from Microchip Tech, in a TO-92. 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 | VDD | power_in | The operating voltage as specified in the DC Electrical Characteristics table is applied to VDD, which is 3.1V to 5.5V for the MCP9701/9701A. |
| 2 | VOUT | output | The sensor output is measured at VOUT, with a voltage range of 200 mV to 3V over the operating temperature range for the MCP9701/9701A. |
| 3 | GND | power_in | GND is the system ground pin (power ground). |
