DESCRIPTION
The L6932 Ultra Low Drop Output linear regulator op-
erates from 2V to 14V and is able to support 2A. De-
signed with an internal 50m
N-channel
Mosfet, can be usefull for the DC-DC conversion be-
tween 2.5V and 1.8V at 2A in portable applications
reducing the power dissipation.
L6932 is available in 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.
