N° Type 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 1.23 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.
