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 | VOUT | output | Active-low, open-drain reset output. Pulls low when VDD is below the 4.38 V trip point and releases (goes high-impedance) when VDD rises above the threshold plus hysteresis. Requires an external pull-up resistor (typ. 100 kΩ); VOL ≤ 0.4 V at IOL = 500 µA; open-drain leakage IOD ≈ 0.1 µA. |+| 2 | VSS | power_in | Ground / negative supply reference. |+| 3 | VDD | power_in | Positive supply and monitored voltage input. Operating range 1.0 V to 5.5 V, absolute maximum 7.0 V. Detector compares this rail against the internal 4.38 V (450 option) trip threshold. Operating current IDD ≤ 1.75 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `MCP111T-450ETT`+- `MCP111T-450ELT`+- `MCP111T-450ELB`+- `MCP111T-450EMB`+- `MCP111T-450ETO`++## CAD (KiCad official)++- Symbol: `MCP111T-450E`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip datasheet](docs/mcp111t-450e-datasheet.pdf) (32 pp, sha256 `8cfcaedafe808931`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
