Pin Definitions and Functions

Symbol

Function

I

Supply Voltage Input; Input for battery or a pre-regulated

voltage of a e.g. a DC to DC converter.

For compensating line influences, a capacitor to GND close

to the IC pins is recommended.

EN

Enable Input; a high signal turns on the IC, with a low signal

the tracking regulator is turned off.

GND

Ground; connect to TAB.

ADJ

Adjust Input; input for the reference voltage which can be

connected directly or by voltage divider to the reference (see

“Application Information” on Page 8).

Q

Regulator Output; block to GND with a capacitor close to the

IC pins, respecting the values given for its capacitance CQ

and ESR in table “Functional Range” on Page 5.

–

Connect to GND and heatsink area.
