Power Management IC Series for Automotive Body Control High Voltage LDO Regulators BD3570FP, BD3570HFP, BD3571FP, BD3571HFP, BD3572FP, BD3572HFP BD3573FP, BD3573HFP, BD3574FP, BD3574HFP, BD3575FP, BD3575HFP ●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 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 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/HFP BD3572FP/HFP BD3573FP/HFP BD3574FP/HFP BD3575FP/HFP Output voltage 3.3V 5.0 V Variable 3.3V 5.0 V Variable SW function - - - 〇 〇 〇 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 Power dissipation Pd 1.2 (TO252-3) ※3 W 1.3 (TO252-5) ※4 1.6 (HRP5) ※5 Operating temperature range Topr -40 to +125 ℃ Storage temperature range Tstg -55 to +150 ℃ Maximum junction temperature Tjmax 150 ℃ ※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).
