Description
Test Pin. There are actual connections in TP pins, but they are reserved for factory testing purposes. Users should not
connect anything to TP pins; otherwise, the device may not function properly.
Input Voltage.
No Internal Connect. NICs have no internal connections.
Ground Pin = 0 V.
Trim Terminal. It can be used to adjust the output voltage over a ±0.5% range without affecting the temperature
coefficient.
