Description

The LD59030 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

135 mV at V_OUT= 3.3 V.

Maturity status link

LD59030

It is available in DFN4 1x1 package, allowing the maximum space saving.

The device works 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 and output current fold-back protection, make the LD59030 suitable for low

power battery-operated applications.

An enable logic control function puts the LD59030 in shutdown mode allowing a total

current consumption lower than 0.03 µA.
