DESCRIPTION

The L6932 Ultra Low Drop Output linear regulator

operates from 2V to 14V and is able to support 2A.

Designed with an internal 50mΩ N-channel

Mosfet, can be usefull for the DC-DC conversion

between 2.5V and 1.5V at 2A in portable applica-

tions reducing the power dissipation.

L6932 is available in 1.5V, 1.8V, 2.5V and adj ver-

sion from 1.2V and ensure a voltage regulation ac-

curacy of 1%.

The current limit is fixed at 2.5A to control the cur-

rent in short circuit condition within ±8%. The cur-

rent is sensed in the power mos in order to limit the

power dissipation.

The device is also provided of a thermal shut down

that limits the internal temperature at 150°C with

an histeresys of 20°C. L6932 provides the Enable

and the Power good functions.
