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 voltage supply, 1.6 V to 6.0 V. Bypass to GND with a 1 µF ceramic capacitor placed close to the IN and GND pins for best transient response and to minimize input impedance. |+| 2 | GND | power_in | Common ground reference for the device. All voltages are measured with respect to this pin. |+| 3 | EN | input | Enable input, 0 V to 6.0 V. A low voltage (< VEN(LOW)) turns the regulator off and discharges OUT to GND; a high voltage (> VEN(HI)) enables the regulator. An internal 500 kΩ pulldown holds the regulator off by default and is disconnected once VEN > VEN(HI) to reduce input current. |+| 4 | NC | unconnected | No internal electrical connection. May be left floating or tied to a plane; making no connection is preferred. |+| 5 | OUT | power_out | Regulated output voltage (1.8 V for TPS7A2018). Requires a low-ESR ceramic capacitor (1 µF nominal, 0.47 µF to 200 µF effective, ESR ≤ 100 mΩ) to GND placed close to the OUT and GND pins for stability. An internal 150 Ω (typical) pulldown discharges VOUT in shutdown (VEN < VEN(LOW)). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5L |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TPS7A2018PDBVRDBVR`+- `TPS7A2018PDBVRDBVT`+- `TPS7A2018PDBVRDQN`+- `TPS7A2018PDBVRYCJ`+- `TPS7A2018PDBVRYCK`++## CAD (KiCad official)++- Symbol: `TPS7A2018PDBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5L (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/tps7a2018p.pdf) (57 pp, sha256 `0c6942715f398ba4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
