Description
1
OUT
Regulator output.
2
SYNC
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 1.23V. An external resistive divider is required for higher
output voltages.
6VREF
3.3V VREF. No cap is requested for stability.
7
GND
Ground.
8
VCC
Unregulated DC input voltage.
