Mosfet, can be usefull for the DC-DC conversion between 2.5V and 1.5V at 2A in portable applications reducing the power dissipation. L6932 is available in 1.5V, 1.8V, 2.5V and adj version from 1.2V and ensure a voltage regulation accuracy of 1%. The current limit is fixed at 2.5A to control the current in short circuit condition within 8%. The current 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.

DESCRIPTION The L6932 Ultra Low Drop Output linear regulator operates from 2V to 14V and is able to support 2A. Designed with an internal 50m N-channel TYPICAL OPERATING CIRCUIT
