This is an internally regulated and monitored reference voltage supply for external devices.
This reference output can be switched on/off by application.
Overcurrent
External voltage protection
Errors are indicated with a fault signal
The level of the output voltage can be monitored by application.

Note 1: When output voltage is under overload conditions, for example, short circuit to supply voltages. Exceeding the max value might cause damage to output.
Note 2: Current limit for overcurrent protection to limit internal power dissipation.
Note 3: When the limit is exceeded, the output current is regulated. In regulation, the output is switched into overcurrent mode.
Note 4: The measurement is scaled down before the conversion. The effect is compensated in Epec software libraries. For more information, see Epec Programming and Libraries manual.
