which provides the reference voltage for output regulation.
Connect these pins to either open-drain or active pull-up
type outputs. Pulling these pins above 2.9V can cause a
reference offset inaccuracy.
OFS
Connecting a resistor between this pin and ground creates a
positive offset voltage which is added to the DAC voltage,
allowing easy implementation of load-line regulation. For no
offset, simply tie this pin to ground.

OVP
Over-voltage protection pin. This pin pulls to VCC and is
latched when an over-voltage condition is detected. Connect

The internal error amplifier inverting input and output
respectively. Connect the external R-C feedback
compensation network of the regulator to these pins.
IOUT
The current carried out of this pin is proportional to output
current and can be used to incorporate output voltage droop
