CMOS LDO regulators have auto power-save

The BHxxPB1 series of CMOS LDO regulators feature a proprietary automatic power-saving function that dynamically switches performance characteristics based on operating conditions. It combines the benefits of LDOs with low average power consumption. During high-speed operation, with operating current of 20 µA, the output voltage is regulated to ±1% over step load changes. In the power-save mode, the operating current is reduced to 2 µA. The devices suit portable applications such as cell phones.

The LDO regulator series is offered in nine models with fixed output voltages ranging from 1.2 to 3.3 V. The models feature a built-in shutdown function, 8–kV ESD protection, and foldback over-current and thermal protection. ($0.23 ea/small OEM qty — available now.)
