Symbol
Function
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,

n.c.
not connected
connect to GND
4FB
(version EJ A)
Feedback input (version EJ A only).
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.)
4ST
(version EJ S)
Tracking Regulator Status Output (version GS only).
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.
5EN/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).
6GND
Ground reference.
Interconnect the pins on PCB. Connect to heatsink area.
8I
Input.
IC supply. For compensating line influences, a capacitor close to the IC terminals is
recommended.
