Low Drop Voltage Tracker
Features
Functional Description
The TLE 4251 is a monolithic integrated low drop voltage
tracker in the very small SMD package PG-TO252-5-1. It
is designed to supply e.g. sensors under the severe
conditions of automotive applications. Therefore the
device is equipped with additional protection functions against overload, short circuit and
reverse polarity.
Supply voltages up to 40 V are tracked to a reference voltage given to the adjust input
via an external resistor.
The output is able to drive loads up to 400 mA while it follows e.g. the 5 V output of a
main voltage regulator within an accuracy of 0.5%. For loads up to 300 mA the tracking
accuracy is 0.2%.
The TLE 4251 can be switched in stand-by mode via the enable EN input which causes
the current consumption to drop to very low values. This feature makes the IC suitable
for low power battery applications.
