BCT2028EUK30-TR

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

BCT2028EUK30-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 2.5V to 5.5V, and it should be bypassed with a 1uF capacitor to GND.
2 GND power_in Ground reference pin for the regulator.
3 EN input Shutdown input: a logic low reduces the supply current to 10nA, the LDO turns on above 1.5V and shuts down below 0.3V, and it should be connected to IN for normal operation.
4 BP passive Reference-noise bypass for the fixed-voltage version; bypass with a low-leakage 0.01uF ceramic capacitor to GND for reduced output noise.
5 OUT power_out Regulator output.
