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 disable 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.
3.3 V V
Ground.
Unregulated DC input voltage.
