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 | GND | power_in | Ground reference for all signals, 0 V. |+| 2 | /RESET | output | Active-low logic output (ADM811 variant). RESET remains low while VCC is below the reset threshold or when /MR is low; RESET then remains low for at least 140 ms after VCC rises above the reset threshold. VOL <= 0.3 V @ ISINK = 1.2 mA; VOH >= 0.8*VCC @ ISOURCE = 500 uA. |+| 3 | /MR | input | Manual Reset. Active-low debounced input; ignores input pulses of 100 ns or less (typical) and is guaranteed to accept input pulses greater than 10 us. Internally pulled up (10-30 kOhm typ 20 kOhm). Leave floating when not used. |+| 4 | VCC | power_in | Monitored supply voltage (2.5 V, 3 V, 3.3 V, or 5 V options; 2.63 V typical reset threshold for the R variant). A 0.1 uF decoupling capacitor between VCC and GND is recommended. Absolute maximum VCC = -0.3 V to +6 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | SOT-143 |+| Category | Power Supply Chip |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `ADM811RARTZ-REEL7`++## CAD (KiCad official)++- Symbol: `ADM811RARTZ-REEL7`+- Footprint: `Package_TO_SOT_SMD:SOT-143`+- 3D model: SOT-143 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8589805484124909568) (12 pp, sha256 `b82418ebee2a8f6b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
