Note: 
1.  See  thermal  regulation  specification  for  changes  in  output  voltage  due  to  heating  effects.  Line  and  load 
regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is 
measured at the output lead = 1/18” from the package. 
2.  Line  and  load  regulation  are  guaranteed  up to  the  maximum  power dissipation  of  15W.  Power dissipation  is 
determined  by  the  input  /  output  voltage  difference  and  the  output  current.  Guaranteed  maximum  power 
dissipation will not be available over the full input / output voltage range. 
3.  Quiescent current is defined as the minimum output current required to maintain the regulation. 
4.  The  Output  Capacitor  does  not  have  a  theoretical  upper  limit  and  increasing  its  value  will  increase  stability.

=100uF or more is typical for high current regulator design.
