The LX8211A adjustable voltage
linear regulator combines low dropout,
high accuracy, very low ground current
and fast response in a very small
footprint.
Using the Enable pin the regulator is
switched on with TTL logic levels,
which is especially useful for battery-
operated equipment.
Other features
include independent thermal and short
circuit current protection. The regulator
is stable with a low value ceramic output
capacitor.
The PNP output transistor allows for
ultra low dropout typically less than
140mV at 100mA.
