BCT2193EUR33-TR from BROADCHIP, in a SOT-23-3. 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 | GND | power_in | Ground pin for the regulator, the reference for the 1.6V to 5.5V input and the 3.3V fixed output. |
| 2 | OUT | power_out | Regulator output, fixed at 3.3V for the BCT2193EUR33-TR, with up to 500mA output current. |
| 3 | IN | power_in | Regulator input; supply voltage can range from 1.6V to 5.5V, so bypass with a 1μF capacitor to GND. |
