Regulator output
Master/slave synchronization
A logical signal (active high) disables the device. If INH is not used the
pin must be grounded. When it is open, an internal pull-up disables the
device
E/A output for frequency compensation
Feedback input. Connecting directly to this pin results in an output
voltage of 1.23 V. An external resistive divider is required for higher
output voltages
