P-TO252-5-1
Short Functional Description
The TLE 4252 is a monolithic integrated low-drop voltage tracking regulator in a very
small SMD package P-TO252-5-1. It is designed to supply off-board systems, e.g.
sensors in engine management systems under the severe conditions of automotive
applications. Therefore the device is equipped with additional protection functions
against reverse polarity and short circuit to GND and battery.
With supply voltages up to 40 V the output voltage follows a reference voltage applied at
the adjust input with high accuracy. The reference voltage applied directly to the adjust
input or by an e.g. external resistor divider can be 1.5 V at minimum.
The output is able to drive loads up to 250 mA at minimum while they follow e.g. the 5 V
output of a main voltage regulator as reference with high accuracy.
The TLE 4252 tracker can be switched into stand-by mode to reduce the current
consumption to very low values. This feature makes the IC suitable for low power battery
applications.
