TYPICAL APPLICATION CIRCUIT

* LR3966 can deliver a continuous current of 3.0A over the full operating temperature. However, the output current is

limited by the restriction of power dissipation which differs from packages. A heat sink may be required depending

on the maximum power dissipation and maximum ambient temperature of application. With respect to the applied

package, the maximum output current of 3.0A may be still undeliverable.

Pull-Up resistor should be kept under 10kΩ.
