Description
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.
Regulator feedback pin. Compares a percentage of the regulator output to the internal 1.2V voltage reference.
Internal resistors are used to program the desired regulator output voltage.
Buffer inputs. Normally floating.
Buffer inputs. Normally floating.
