General part information

The LDLN030 is a 300 mA very low-dropout voltage regulator, able to work with an input voltage ranging from 1.6 V to 5.5 V.

The typical dropout voltage at 300 mA load is 150 mV.

The very low quiescent current, which is just 16 μA at no load, extends battery-life of applications requiring very long standby time.
