BCT2020EUK28-TR

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

BCT2020EUK28-TR from BROADCHIP, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN power_in Regulator input; supply voltage can range from 1.6V to 5.5V, and it should be bypassed with a 1μF capacitor to GND.
2 GND power_in Ground.
3 EN input Enable pin with an internal pull-down resistor; a logic low reduces the supply current to less than 1μA, and it should be connected to IN for normal operation.
4 BP passive Reference-noise bypass pin (fixed-voltage version only); bypass with a low-leakage 0.01μF ceramic capacitor placed very close to the pin for reduced output noise and high PSRR.
5 OUT power_out Regulator output.
