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 the regulator. Connect to system ground; the device references its output and internal Vref to this pin. |+| 2 | VOUT | power_out | Regulated output voltage, 3.6V nominal (3.492V min / 3.708V max) at IOUT=40mA. Delivers up to 450mA. Recommended output capacitor for stability (see application section). |+| 3 | VIN | power_in | Supply input voltage. Absolute max 15V; recommended operating max 12V. Minimum input ~4.5V for 3.6V output regulation (VOUT + dropout ~80mV). Bypass with a small ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-89-3 |+| Category | PMIC |+| Pins | 3 |++## CAD (KiCad official)++- Symbol: `HT7836-A`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UMW datasheet](docs/ht7836-a-datasheet.pdf) (12 pp, sha256 `0ddd2116b6d87a09`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
