BD357XFP/HFP SERIES regulators feature a high 50 V withstand-voltage and are suitable for use with onboard vehicle
microcontrollers. They offer the output current of 500 mA while limiting the quiescent current to 30μA (TYP).With these
devices, a ceramic capacitor can be selected at the output for stable operation, the output tolerance is within ±2% over the
wide ambient temperature range (-40 to 125℃), and the short circuit protection is folded-type to minimize generation of
heat during malfunction. These devices are developed to offer most robust power-supply design under the harsh
automotive environment. The BD357XFP/HFP Series provide ideal solutions to lower the current consumption as well as to
simplify the use with battery direct-coupled systems.
