* TJ4220 can deliver a continuous current of 2A 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 2A may be still undeliverable.
* See Application Information.
