LDL112:1.2 A low quiescent current LDO with reverse current protection

The LDL112 is a low-dropout linear regulator, which can provide a maximum current of 1.2 A, with a typical dropout voltage of 300 mV.

It is stabilized with a ceramic capacitor on the output.

The very low drop voltage, low quiescent current and reverse current protection features make it suitable for low power battery-powered applications.

The enable logic control function puts the LDL112 in shutdown mode allowing a total current consumption lower than 1 µA.

The device is equipped with current limit and thermal protection.

Key Features
