BCT2211EUK33-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 with a supply voltage range of 1.6V to 5.5V; bypass it with a 1µF capacitor to GND. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Enable pin with an internal pull-down resistor; a logic low (VIL max 0.4V) reduces supply current to less than 1µA, so connect it to IN for normal operation. |
| 4 | BP | passive | Reference-noise bypass pin on the fixed-voltage versions; 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; the 3.3V fixed output for this part number is delivered here, with a 1µF output capacitor per the typical application circuit. |
