DESCRIPTION
KEY FEATURES
W W W.

.COM
The LX8211 fixed/adjustable voltage
linear regulators combines low dropout,
high accuracy, ultra-low ground current
and fast response in a very small
footprint.
Using the Enable pin the regulators 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
capacitors.
For ultra low noise operation a Bypass
pin is brought out to connect an optional
capacitor.
Significant performance
improvements over Bipolar technology
are achieved designing in CMOS:
increased regulator efficiency by
minimizing operating ground current
(typ<140uA) and it is nearly eliminated
(typ<1uA) in shutdown. The PMOS
output transistor allows for ultra low
dropout typically less than 300mV at
100mA.
