Description
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.
Features
1) Ultra-low quiescent current: 30μA (TYP.)
2) Low-saturation voltage type P-channel DMOS output transistors
3) High output voltage precision: 2%Iomax = 500 mA
4) Low-ESR ceramic capacitors can be used as output capacitors.
5) Vcc power supply voltage = 50 V
6) Built-in overcurrent protection circuit and thermal shutdown circuit
7) TO252-3, TO252-5, HRP5 Package
Applications
Onboard vehicle devices (body-control, car stereos, satellite navigation systems, etc.)
