BCT2038EUK33-TR

BROADCHIP · Linear Voltage Regulators (LDO) · SOT-23-5

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.
