zDescription BD394□FP Series
regulators feature a high 36 V breakdown voltage and are compatible with onboard vehicle microcontrollers.
They offer an output current of 500 mA while limiting dark current to 30 µA (TYP).
The series supports the use of ceramic capacitors as output phase compensation capacitors.
Since the ICs use P-channel DMOS output
transistors, increased loads do not result in increased total supply current.
BD394□FP Series is ideal for lowering current consumption and costs in battery direct-coupled systems.
