BHXXPB1WHFV_09 Datasheet, PDF (1/10 Pages) Rohm – CMOS LDO Regulators with Auto Power Saving Function

CMOS LDO Regulator Series for Portable Equipments
CMOS LDO Regulators
with Auto Power Saving Function
BH□□PB1WHFV Series
No.09020EAT05
Description
The BH□□PB1WHFV regulator series can respond to changes in output current by switching to a state in which regulator
characteristics are ideal. The regulators cut power consumption by lowering their own current consumption to approximately
2 A when the application is operating in the standby state. During normal-current operation it will automatically switch to
high-speed operating mode. The IC's soft start function reduce the rush current that flows to the output capacitors during
startup. The HVSOF5 package, which features excellent heat dissipation, contributes to space-saving application designs.
Features
1) Automatic switching between low-consumption and high-speed modes
2) Built-in rush current prevention circuit
3) Low-voltage 1.7 V operation
4) High accuracy output voltage: ± 1%
5) Circuit current during low-consumption operation: 2 A
6) Stable with a ceramic capacitor (0.47 F)
7) Built-in temperature and overcurrent protection circuits
8) Built-in output discharge during standby operation function
9) Ultra-small HVSOF5 power package
Applications
Battery-driven portable devices, etc.
