CMOS LDO Regulators with
Automatic Power-Saving Function
ROHM’s CMOS LDO regulators (BHxxPB1 Series) feature
a proprietary automatic power-saving (APS) function that
dynamically switches performance characteristics based
on operating conditions. The series combines the benefits
of LDOs — small packaging, minimal external components
and a simple design process — with very low average
power consumption.
Key Features
Portable devices
• PDAs
• Mobile phones
• Digital cameras
• Digital video cameras
• Low-voltage reference source enables stable operation from
1.7V input
• Integrated output discharge function eliminates the external
blocking diodes required to prevent reverse-voltage damage
• Equipped with inrush current protection for output stability
without the need for external components
• HVSOF5 package requires 70% less mounting area than the
standard SOT23-5
