BD3573FP Datasheet | ROHM

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 m A 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 m A 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.) - Line up matrix BD3570FP/HFP BD3571FP/HFP BD3572FP/HFP BD3573FP/HFP BD3574FP/HFP BD3575FP/HFP Output voltage SW function Package HFP:HRP5 3.3V － FP:TO252-3,TO252-5 5.0 V － Variable － 3.3V 〇 5.0 V 〇 Variable 〇 - Absolute maximum ratings (Ta=25℃) Parameter Supply voltage Switch Supply voltage Output current Power dissipation Operating temperature range Storage temperature range Maximum junction temperature ※1 ※2 ※3 ※4 ※5 Symbol VCC VSW IO Pd Topr Tstg Tjmax Limit 50 50 500 1.2 (TO252-3) ※3 1.3 (TO252-5) ※4 1.6 (HRP5) -40 to +125 -55 to +150 150 ※5 ※1 ※2 Unit V V m A W ℃ ℃ ℃ Not to exceed Pd and ASO. for ON/OFF SW Regulator only TO252-3: Reduced by 9.6 m W/℃ over 25 ℃, when mounted on a glass epoxy board (70 mm  70 mm  1.6 mm)....
