LD39030DTPU33R

LD39030DTPU33R is high accuracy voltage regulator providing 300mA of maximum current from an input voltage ranging from 1.5V to 5.5V, with a typical dropout voltage of 300mV. It is available in DFN4 1 x 1 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 softstart 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 1µA. Constant current and thermal protection are provided. Applications include mobile phones, tablets, digital still cameras (DSC), cordless phones and similar battery-powered systems, portable media players.
