BCT2038EUK33-TR from BROADCHIP, in a SOT-23-5. 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. |
