6.1
The TLE8458G has a monolithic integrated voltage regulator dedicated for microcontroller supplies under harsh
automotive environment conditions. Due to its ultra low current consumption, the TLE8458Gx is perfectly suited
for applications permanently connected to a battery. Additionally, the regulator is switched off in Sleep Mode to
achieve a very low quiescent current. The TLE8458Gx is equipped with protection functions against overloading,
short circuits, and over temperature.
