Linear Regulator Provides Low Quiescent Current In Portables

To help meet the demand for power management in battery-powered applications, the UCC386/7/8 is a low-dropout, 200-mA linear regulator that's well-suited to battery-powered, handheld equipment such as cellular phones, pagers, PDAs and other portable instruments. Fabricated with BiCMOS technology, the chip is tailored for low-dropout applications where extremely low quiescent power is required. Suited for low input to output differential applications, the device will pass 200 mA while requiring input voltage headroom of only 200 mV.
