ROHM BD3571FP-E2

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 30 μA (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 °C), 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.
