Pin Symbol Function
1ADJ/ENAdjust / Enable.
Connect the reference to this pin. A low signal disables the IC; a high signal switches it on.
The reference voltage can be connected directly or by a voltage divider for lower output voltages.
For compensating line influences, a capacitor close to the IC pins is recommended.
2GND Ground Reference.
Internally connected to Pin 5. Connect to heatsink area.
3I Input.
IC supply. For compensating line influences, a capacitor close to the IC pins is recommended.
4Q Tracker Output.
Block to GND with a capacitor close to the IC terminals, respecting capacitance and ESR
requirements given in the table “Functional Range”.
5GND Ground Reference.
Internally connected to Pin 2. Connect to heatsink area.
