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 | Regulator Input. Supply voltage 1.6V to 5.5V. Bypass with a 1µF capacitor to GND. |+| 2 | GND | power_in | Ground reference for the regulator. |+| 3 | EN | input | Enable Pin with internal pull-down resistor. A logic low reduces the supply current to less than 1µA. Connect to IN for normal operation. |+| 4 | BP | passive | Reference-Noise Bypass Pin (fixed voltage version). Bypass with a low-leakage 0.01µF ceramic capacitor placed close to the pin for reduced output noise and high PSRR. |+| 5 | OUT | power_out | Regulator Output. Fixed 3.3V, up to 500mA load current. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BROADCHIP |+| Package | SOT-23-5 |+| Category | Power Supply Chip |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `BCT2038EUK33-TREUK12-TR`+- `BCT2038EUK33-TREUK18-TR`+- `BCT2038EUK33-TREUK28-TR`+- `BCT2038EUK30-TR`+- `BCT2038EUK33-TR`+- `BCT2038EUK33-TREUKAJ-TR`+- `BCT2038EUK33-TREUR12-TR`+- `BCT2038EUK33-TREUR18-TR`+- `BCT2038EUK33-TREUR28-TR`+- `BCT2038EUK33-TREUR30-TR`+- `BCT2038EUK33-TREUR33-TR`+- `BCT2038EUK33-TREXK12-TR`+- `BCT2038EUK33-TREXK18-TR`+- `BCT2038EUK33-TREXK28-TR`+- `BCT2038EUK33-TREXK30-TR`+- `BCT2038EUK33-TREXK33-TR`+- `BCT2038EUK33-TREXKAJ-TR`+- `BCT2038EUK33-TREJR12-TR`+- `BCT2038EUK33-TREJR18-TR`+- `BCT2038EUK33-TREJR28-TR`+- `BCT2038EUK33-TREJR30-TR`+- `BCT2038EUK33-TREJR33-TR`++## CAD (KiCad official)++- Symbol: `BCT2038EUK33-TR`+- 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:** [BROADCHIP datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588944575184441344) (18 pp, sha256 `85f29f031228797a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
