**Analog Devices** · Supervisor And Reset ICs · SOT-23-3

ADM1811-5ARTZ-RL7 from Analog Devices, 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 | RST | output | Active low reset output, open-drain with internal pull-up resistor (3.5 kΩ to 7.5 kΩ, 5.5 kΩ typical for ADM1811); RST remains low while VCC is below the reset threshold and for 150 ms typical after VCC rises above the reset threshold. |
| 2 | VCC | power_in | Supply voltage being monitored; the datasheet specifies a 1.2 V to 5.5 V supply range over −40°C to +105°C. |
| 3 | GND | power_in | 0 V ground reference for all signals. |
