Description
Regulator Feedback. Compares a percentage of the regulator output to the internal 1.2 V voltage
reference. Internal resistors are used to program the desired regulator output voltage.
Ground. Normally 0 V.
Supply Voltage. Normally 16 V.
Regulator output voltage. Provides reference voltage to resistor string and is internally connected to
the top of the resistor string.
Buffer inputs. Normally floating.
Ground. Normally 0 V.
Supply Voltage. Normally 16 V.
