Power Management IC Series for Automotive Body Control High Voltage LDO Regulators BD3570FP, BD3570HFP, BD3571FP, BD3571HFP, BD3572FP, BD3572HFP BD3573FP, BD3573HFP, BD3574FP, BD3574HFP, BD3575FP, BD3575HFP No.11036EBT02 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 30A (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: 30A (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.) Line up matrix BD3570FP/HFP BD3571FP/HFPBD3572FP/HFPBD3573FP/HFP BD3574FP/HFP BD3575FP/HFP Output voltage 3.3V 5.0 V Variable 3.3V 5.0 V Variable SW function Package FP:TO252-3,TO252-5 HFP:HRP5 Absolute maximum ratings (Ta=25) Parameter Symbol Limit Unit Supply voltage VCC 50 1V Switch Supply voltage VSW 50 2V Output current IO 500 mA 1.2 (TO252-3) 3 Power dissipation Pd 1.3 (TO252-5) 4 W 1.6 (HRP5) 5 Operating temperature range Topr -40 to +125 Storage temperature range Tstg -55 to +150 Maximum junction Tjmax 150 temperature 1 Not to exceed Pd and ASO. 2 for ON/OFF SW Regulator only 3 TO252-3: Reduced by 9.6 mW/ over 25 , when mounted on a glass epoxy board (70 mm 70 mm 1.6 mm). 4 TO252-5: Reduced by 10.4 mW/ over 25 , when mounted on a glass epoxy board (70 mm 70 mm 1.6 mm). 5 HRP5: Reduced by 12.8 mW/ over 25 , when mounted on a glass epoxy board (70 mm 70 mm 1.6 mm). www.rohm.com 2011.03 - Rev.B 1/9 2011 ROHM Co., Ltd.
