Short-circuit protection Test Pin 1 and Test Pin 5 are reserved for in-package Zener zap.
To achieve the highest level of accuracy at the output, the Zener
zapping technique is used to trim the output voltage. Because
each unit may require a different amount of adjustment, the
resistance value at the test pins varies widely from pin to pin
and from part to part. The user should leave Pin 1 and Pin 5
unconnected.
