DESCRIPTION
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.
