Note 1: Input Voltage is recommended operating at 15V max.

Note2 : Operating Junction Temperature is recommended at -40° C to 125° C.

Note3: PD(Max)=(TJ(max)-TA)/

,PD(Max):Maximum Power Dissipation; TA: Ambient Temperature,

TJ(max): Maximum Junction Temperature ;

:The Junction-to Ambient Thermal Resistance.

Exceeding the maximum allowable power dissipation will result in die temperature and the Regulator

will go into thermal shutdown
