current regulation.
Unused inputs should be connected to proper
voltage levels in order to get the highest noise im-
munity.
As the circuit operates with switch mode current
regulation,
interference
generation
might arise in some applications. A good measure
might then be to decouple the circuit with a 100nF
capacitor, located near the package between
power line and ground.
