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 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.
