# ADM1812-5ARTZ-RL7

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

ADM1812-5ARTZ-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 high reset output for the ADM1812: RST remains high 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 supply range of 1.2 V to 5.5 V over −40°C to +105°C. |
| 3 | GND | power_in | 0 V ground reference for all signals. |
