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 1.23V. An extenal resistive divider is required for higher output

voltages.

6VREF

7

GND

Ground.

8

VCC

Unregulated DC input voltage.
