Reference voltage adjustment
Voltage adjusting pin for the
incorporated reference voltage
generating circuit. The output
voltage of V

Output
Reference voltage output
Voltage output pin of the incorpo-
rated reference voltage generating
circuit. This pin has high output
impedance, and must be connected
with a high impedance element.
