General Description
The ILC7280 is two independent 150mA low dropout
(LDO)voltage regulators in an 8-pin MSOP package. Each
regulator output is independently short circuit protected and
has independent enable lines. The device offers a unique
combination of low dropout voltage and low quiescent
current offered by CMOS technology as well as the low
noise and good ripple rejection characteristics of bipolar
LDO regulators.
The ILC7280 is available in a space saving MSOP-8
package.
