Pin Description
A resistor divider from this pin to the Cathode pin and
ground sets the output voltage.
The output of the shunt regulator .A minimum of 1uF
capacitor must be connected from this pin to Anode pin
to insure unconditional stability.
Ground pin. This pin must be connected to the lowest
potential in the system & all other pins must be at higher
potential with respect to this pin.
These pins are not connected internally.
