TLE4254GSXT Description
The OPTIREG? linear TLE4254GSXT 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 circuits to GND and battery. With supply voltages up to 40 V, the output voltage follows a reference voltage applied at the adjusted input with very high accuracy. The reference voltage applied directly to the adjusted input or by an e. g. external resistor divider can be 2.0 V at minimum.
