Description
The TLE42764 is a monolithic integrated low dropout voltage regulator
for load currents up to 400 mA. An input voltage up to 40 V is regulated
to an adjustable or 5 V fixed voltage with a precision of ±2%. The device
is designed for the harsh environment of automotive applications.
Therefore it is protected against overload, short circuit and
overtemperature conditions by the implemented output current limitation
and the overtemperature shutdown circuit. The TLE42764 can be also
used in all other applications requiring a stabilized voltage between 2.5 V
and 20 V.
Due to its very low quiescent current the TLE42764 is dedicated for use
in applications permanently connected to
V
BAT
. In addition the device can
be switched off via the Enable input reducing the current consumption to
less than 10 μA.
