LD39130S

300 mA very low quiescent current Linear regulator IC with automatic Green mode

快速浏览资源

The LD39130S is a high accuracy voltage regulator that provides 300 mA maximum current from an input voltage ranging from 1.4 V to 5.5 V, with a typical dropout voltage of 300 mV.

It is available in DFN6 1.2 x 1.3 mm package and in ultra-small CSP 4 bumps 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 make it suitable for low power battery-operated applications. It integrates an internal logic circuitry, which allows the regulator to be in ultra-low consumption mode (green mode), when the output current required is very low. The normal working mode, with fast transient response, is restored when the load current increases.

The enable logic control function puts the LD39130S in shutdown mode allowing a total current consumption lower than 0.1 µA. The current foldback and thermal protection are provided.
