N Pin Description
1 OUT Regulator output.
2 SYNCH Master/slave synchronization.
3INH
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.
4 COMP E/A output for frequency compensation.
5FB
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.
6 VREF 3.3 V V
REF. No cap is requested for stability.
7 GND Ground.
8 VCC Unregulated DC input voltage.
