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 | IN | power_in | Input supply to the regulator. Recommended input voltage range 2.7 V to 5.5 V; absolute maximum 6 V. Bypass with a 0.1-µF to 1-µF ceramic capacitor to GND. |+| 2 | GND | power_in | Regulator ground reference. All voltages are measured with respect to this pin. |+| 3 | EN | input | Enable pin. Driving EN high (up to VIN) turns on the regulator; driving it low puts the regulator into shutdown mode. Tie to IN if unused. Absolute maximum -0.3 V to 6 V. |+| 4 | NR | passive | Noise Reduction pin. Connect an external capacitor (up to 10 nF) from this pin to GND to filter noise generated by the internal bandgap reference, improving PSRR and reducing output noise. |+| 5 | OUT | power_out | Regulated output pin. Fixed 1.8-V output at up to 200 mA (TPS79318). Requires a 2.2-µF (minimum) ceramic output capacitor to GND for stability; 10 µF recommended. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TPS79318DBVRDBVR`+- `TPS79318DBVRDBVT`+- `TPS79318DBVRDBVR`+- `TPS79318DBVRDBVT`+- `TPS79318DBVRYZQR`+- `TPS79318DBVRYZQT`++## CAD (KiCad official)++- Symbol: `TPS79318DBVR`+- 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/tps79318.pdf) (33 pp, sha256 `49694a90e8294ec9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
