Pin Function
Disable pin is internally pulled to V_IN resulting in standby mode and the output will be
disabled. Grounding this pin will enable the output.
Ground.
Mode selection pin. Grounding this pin will yield V_o = 1.515*V_in. Pulling this pin to V_IN will
yield V_O = 1.32*V_IN. An external voltage divider connected at V_IN will achieve:
