BCT2036EUK18-TR

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

BCT2036EUK18-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, specified from 1.6V to 5.5V and to be bypassed with a 1µF capacitor to GND; IN to GND is rated -0.3V to 6.0V.
2 GND power_in Ground reference pin for the regulator.
3 EN input Enable input with an internal pull-down resistor; a logic low reduces supply current to less than 1µA, it must be connected to IN for normal operation, and EN to GND is rated -0.3V to 6.0V.
4 BP/FB passive On the fixed-voltage version this is the reference-noise bypass pin (BP), to be bypassed with a low-leakage 0.01µF ceramic capacitor placed close to the pin; on the adjustable version it is the feedback pin (FB) that sets the output voltage with a 0.8V typical feedback voltage.
5 OUT power_out Regulator output, delivering up to 300mA maximum output current at the selected fixed or adjustable (0.8V to 5.0V) output voltage.
