Regulator output.
Master/slave synchronization.
A logical signal (active high) disables the device. If INH not used the pin
must be grounded. When it is open an internal pull-up disable the
device.
E/A output for frequency compensation.
Feedback input. Connecting directly to this pin results in an output
voltage of 1.23V. An external resistive divider is required for higher
output voltages.
3.3V V

. No cap is requested for stability.
Ground.
Unregulated DC input voltage.
