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 disables 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 VREF. No cap is requested for stability.
7
GND
Ground.
8
VCC
Unregulated DC input voltage.
