The LD39030 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 300 mV.
It is available in DFN4 1x1 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 soft-start 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 0.1 µA. Constant current and thermal protection are provided.主要特性
