REVIEW

KEY FEATURES

W W W .

Microsemi

.COM

The LX8221 contains two fixed

voltage linear regulators combines low

dropout, high accuracy, ultra-low ground

current and fast response in a very small

footprint. Each device can be powered

from a separate supply voltage or the

same supply voltage for maximum

system flexibility.

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 regulators are 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<100uA) and it is nearly eliminated

(typ<1uA) in shutdown. The PMOS

output transistor allows for ultra low

dropout typically less than 300mV at

100mA.

!

Compact regulators with two

150 mA outputs

!

Dropout Voltage typically

300mV @ 100mA

!
