I wanted find out what the engineers on 8052 website were using.
that is not what you asked, you asked
type to fit in board foot print to replace

I use the LM2937-3.3 whiich is a reply to "what the engineers" but definitely not an answer to your original question "fit in board".

Also, you drop from 9V, I drop from 5V.

Hi Erik:
That question came from first post in thread in P.S. part any way thanks for your comments.

The foot print of the sbc is 2 inches by 2 inches uncut.
And 1 inch by 2 inch cut. Maybe I am saying this incorrectly.I never worked with foot prints before.
Also is 9v battery to 3.3v regulator to much for 3.3v regulator?
Best regards,

Ralph S

My two cents and then sum            01/01/70 00:00      
   RC reset - asking for trouble!            01/01/70 00:00      
   be careful now ... here be dragons            01/01/70 00:00      
   May we...            01/01/70 00:00      
      yes            01/01/70 00:00      
   Why you should use a proper reset chip            01/01/70 00:00      
      what about bidirectional reset?            01/01/70 00:00      
         I use only external watchdog / brown-out detection            01/01/70 00:00      
            I doubt this.....            01/01/70 00:00      
               If it really, really has to work..            01/01/70 00:00      
            there isn't much you can do about internal reset            01/01/70 00:00      
               which chip is that?            01/01/70 00:00      
                  DS89C4x0, among, I suspect, others            01/01/70 00:00      
               Micro isn't allowed to emit reset signal            01/01/70 00:00      
         easy as apple pie            01/01/70 00:00      
            Only because it worked for you does not mean...            01/01/70 00:00      
               that does not matter            01/01/70 00:00      
                  Of course, it does            01/01/70 00:00      
   all posts in this thread are incomplete            01/01/70 00:00      
      Then, please read again what I wrote            01/01/70 00:00

         Thanks to all who give comments            01/01/70 00:00      
            What kind of supply regulation?            01/01/70 00:00      
               Battery            01/01/70 00:00      
                  Hhm, I'm confused now...            01/01/70 00:00      
                     Right            01/01/70 00:00      
                        if you specified            01/01/70 00:00      
                           I guess a LM78L05 was originally built-in            01/01/70 00:00      
                        Then, the DS275 won't work either            01/01/70 00:00      
            MAX6383            01/01/70 00:00      
   Maybe here            01/01/70 00:00      
      I did look their first            01/01/70 00:00      
         that is not what you asked            01/01/70 00:00      
            Sorry Erik            01/01/70 00:00

                  What photo?            01/01/70 00:00      
                     OOPS            01/01/70 00:00      
                        Always...            01/01/70 00:00      
                           I would like change ds275            01/01/70 00:00

                                 Ok, try this:            01/01/70 00:00      
                                    to Kai            01/01/70 00:00      
                                       Only to avoid damage caused by inrush currents            01/01/70 00:00      
                                          Ah, thanks            01/01/70 00:00      
                                          When you say "damage"            01/01/70 00:00      
                        Sorry Erik            01/01/70 00:00      
                           Would it be just too much of an effort for you            01/01/70 00:00
