Description

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 output. The ultra low drop voltage, low

quiescent current and low noise features,

together with the internal soft-start circuit, make

the LD39030 suitable for low power battery-

operated applications.

An enable logic control function puts the

LD39030 in shutdown mode allowing a total

current consumption lower than 0.1 µA. Constant

current and thermal protection are provided.
