	Erik Malund said: I fail to see a modern design needing that amount of regulated 5V I think you need to qualify that! eg, PC power supplies still give many Amps at 5V... (and even more at 3V) and thus it is no surprise it is discontinued. More likely is that switch-mode designs are now favoured for such applications?

               I think the "H" may be because it is 5A isnt it?              01/01/70 00:00

                           Yes, they did, and those sheets were excellent!              01/01/70 00:00

   Fairchild was the original manufacturer              01/01/70 00:00
   these parts are hybrids ... so you can synthesize them              01/01/70 00:00
