BCT2036EUK33-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 pin. |
| 3 | EN | input | Enable pin with an internal pull-down resistor; a logic low reduces the supply current to less than 1μA, and it must be connected to IN for normal operation. |
| 4 | BP/FB | passive | On the fixed-voltage version this is the reference-noise bypass pin (BP), which should be bypassed with a low-leakage 0.01μF ceramic capacitor placed very close to the pin for reduced output noise and high PSRR; on the adjustable version this pin is FB, used to set the output voltage. |
| 5 | OUT | power_out | Regulator output. |
