5 V Low Drop Voltage Regulator

The TLE7184F incorporates a 5V LDO for µC supply. The voltage regulator is protected against Over Temperature

by the central temperature sensor (see Chapter 9.2.1 and Chapter 9.2.2). It has an integrated current limitation

and Under Voltage detection.

Parameters for Under Voltage detection see Chapter 9.2.5.
