Description

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.
