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.
