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
Ground.
Unregulated DC input voltage.
