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 | OUT | power_out | Power-switch output. Delivers current from IN through the internal 70 mΩ high-side N-channel MOSFET to the load; up to 500 mA continuous with a typical 1 A current limit. |+| 2 | GND | power_in | Ground reference for the device. |+| 3 | OC | output | Overcurrent open-drain fault output, active-low. Asserts (pulls low) after a deglitch delay when the switch enters current-limit or thermal-shutdown. Requires an external pull-up resistor. |+| 4 | EN | input | Enable input. On the TPS2051B (205xB series) EN is active-high: logic high turns on the power switch, logic low disables it. |+| 5 | IN | power_in | Input supply voltage, 2.7 V to 5.5 V. Feeds the internal high-side MOSFET and control circuitry; bypass locally with a 0.1 µF capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TPS2051BDBVRDBVR`+- `TPS2051BDBVRDBVT`+- `TPS2051BDBVRD`+- `TPS2051BDBVRDR`+- `TPS2051BDBVRDGN`+- `TPS2051BDBVRDGNR`++## CAD (KiCad official)++- Symbol: `TPS2051BDBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps2051b.pdf) (74 pp, sha256 `b8e3d6d124f7aa62`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
