BCT2193EUR33-TR

BROADCHIP · Linear Voltage Regulators (LDO) · SOT-23-3

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.
