Description The OPTIREG™ linear TLE4254 is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG-DSO-8 packages. The IC is designed to supply off-board systems, e. g. sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the IC 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 very high accuracy. The reference voltage applied directly to the adjust input or by an e. g. external resistor divider can be 2.0 V at minimum. .infineon./OPTIREG-linear Rev. 1.3 2021-06-15 OPTIREG™ linear TLE4254 High accuracy low dropout voltage tracking regulator The output is able to drive loads up to 70 m A while the device follows with high accuracy the e. g. 5 V output of a main voltage regulator acting as reference.
