LD39030 300mA very low quiescent current linear regulator IC

LD39030 300mA very low quiescent current linear regulator IC

The LD39030 high accuracy voltage regulator provides 300 mA of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 300 mV. It is available in DFN4 1x1 package, allowing the maximum space saving. The device is stabilized with a ceramic capacitor on the.
