Description
The LD39080 is a fast, ultra low drop linear
regulator which operates from 2.5 V to 6 V input supply.
A wide range of output options is available. The low drop voltage, low noise, and ultra low quiescent current make it suitable for low voltage microprocessors and memory applications. The device is developed on the BiCMOS process which allows the low quiescent current operation regardless of the output load current.
