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 | VIN | power_in | Input supply voltage. Operating range 1.2 V to 5.5 V (absolute max 6.5 V vs GND). A 1 uF input capacitor to GND is recommended for stability. |+| 2 | GND | power_in | Device ground reference. Return path for supply and internal control circuitry. |+| 3 | EN | input | Enable control input. VIH >= 2 V (max) enables the regulator; VIL <= 0.6 V (min falling) forces shutdown. EN input current ~10 nA typ at 5 V. Absolute max -0.3 V to 6 V vs GND. Do not float. |+| 4 | SNS | input | Feedback (sense) input for the internal error amplifier; internal reference VFB = 0.8 V. Connect to an external resistor divider from VOUT to set the output: R1 = R2 * (VOUT/0.8V - 1), with R2 < 24 kOhm. SNS input current ~0.7 uA typ. |+| 5 | VOUT | power_out | Regulator output. Delivers up to 600 mA with typical dropout of 0.32 V at 600 mA / VOUT=3.3 V. Stable with a >=1 uF ceramic or tantalum output capacitor. When EN=0, an internal ~100 Ohm discharge resistance pulls VOUT down. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TP172CADJS5S5`++## CAD (KiCad official)++- Symbol: `TP172CADJS5`+- 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:** [TECH PUBLIC datasheet](docs/tp172cadjs5-datasheet.pdf) (9 pp, sha256 `32123534387edee0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
