BCT78L05AEUR-TR

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

BCT78L05AEUR-TR from BROADCHIP, in a SOT-23. 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 VOUT power_out Output voltage pin for the regulation; the datasheet gives an OUT to GND absolute maximum of -0.3V to 5.5V.
2 VIN power_in Input voltage pin for the regulator; the rated input range is 5.5V to 15.0V, with VIN to GND absolute maximum of -0.3V to 16.0V.
3 GND power_in Ground pin for fixed output.
