Datasheet Single-Output LDO Regulators High Voltage LDO Regulators 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 A (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. Features Packages W (Typ) x D (Typ) x H (Max) Low-Saturation Voltage Type P-Channel DMOS Output Transistors High Output Voltage Precision: 2 % (lo = 200 mA) Low-ESR Ceramic Capacitors can be used as Output Capacitors.
