The characteristics of low dropout voltage and fast transient
response to step changes in load make it suitable for low
voltage microprocessor applications. The typical quiescent
current is approximately 0.5mA and changes little with load
current. The built-in current-limit and thermal-shutdown
functions prevent IC from damage in fault conditions.
This device is available in U-DFN2030-8, SO-8EP and
SOT223-3L packages.
