Description
The LD59030 high accuracy voltage regulator provides 300 m A of maximum current from an input voltage ranging from 1.5 V to 5.5 V, with a typical dropout voltage of 135 m V at VOUT = 3.3 V.
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.
