BD357xYFP-M BD357xYHFP-M Series
General Description
BD357xYFP-M BD357xYHFP-M Series regulators feature a high withstand voltage (50 V) and are suitable to use with
onboard vehicle microcontrollers. They offer an output current of 500 mA while limiting the quiescent current to 30 µA (Typ).
With these devices, a ceramic capacitor may be used at the output for stable operation. The output tolerance is within ±2 %
over their operating temperature range (-40 °C to +125 °C). The short circuit protection is folded-type to minimize generation
of heat during malfunction. These devices are developed to offer the most robust power supply design under harsh
automotive environments. The BD357xYFP-M BD357xYHFP-M Series provide an ideal solution to lower current
consumption as well as to simplify the use with battery direct-coupled systems.
