The LX8221 family of dual output
linear
regulators
selection of either fixed or adjustable
output voltages, and combine low
dropout
operation,
performance,
tight
accuracy, and ultra-low ground current
within a very small package footprint.
The PMOS output transistor allows
for an ultra-low dropout characteristic
(e.g., typically less than 175mV at
100mA). The individual regulators can
be powered from either separate supply
voltages or the same supply voltage
between 2.8V to 6V allowing for
maximum system flexibility.
An optional ceramic or tantalum type
capacitor may be connected to each
Bypass pin separately to improve
performance
in
applications.

Overall regulator efficiency has been
improved with a minimized operating
ground current (typ < 140
μ
A per
regulator). Further, this ground current
is virtually eliminated in shutdown mode
(typ < 1
μ
A).
Other safety features include channel
independent Thermal and Short Circuit
Current protection.
Separate Enable pins allow each
regulator to be switched on and off
independently by applying a TTL logic
level control signal to the Enable pin
further enhancing system level power
management.
These features combined with a small
footprint (i.e., 10-pin MSOP package)
make the LX8221 especially useful for
battery-operated equipment such as
cellular telephones, laptop computers
and PDA equipment.
