OUT
Regulator output.

SYNC
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.
4
COMP
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.
6
VREF
3.3V V_REF. No cap is requested for stability.
7
GND
Ground.
8
VCC
Unregulated DC input voltage.
