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.
