1Q

Tracker Output.

Block to GND with a capacitor close to the IC terminals, respecting capacitance and ESR

requirements given in the table “Functional Range”.

2, 3, GND

6, 7

Ground reference.

Interconnect the pins on PCB. Connect to heatsink area.

4 FB

Feedback input (version GA only).

(version GA) Non inverting input of the internal error amplifier to control the output voltage.

Connect this pin directly to the output pin in order to obtain lower or equal output voltages

with respect to the reference voltage.

Connect a voltage divider for higher output voltages than the reference.

(See also application information.)

4 ST

Tracking Regulator Status Output (version GS only).

(version GS) Open collector output. Connect via a pull-up resistor to a positive voltage rail.

A low signal indicates fault condions at the regulator’s output.

5 EN/ADJ

Adjust / Enable.

Connect the reference to this pin. The active high signal of the reference turns on the device;

a low signal disables the IC. The reference voltage can be connected directly or by a voltage

divider for lower output voltages (see application information).

8I

Input.

IC supply. For compensating line influences, a capacitor close to the IC terminals is

recommended.
