TJA1100 pin4&16 ; C26 & C28

Hi community .

I have a question about the TJA1100. Im searching for the use of the two capacitors C26 & C28 shown in the schematic at the end of TR1329.pdf. I ooked up TJA1100.pdf too, but didn't get any answer. It's about the pins 4 & 16. These two pins are for the VDDA(1V8) and VDDD(1V8) and are generated by LDO internally. So what are the two capacitors C26 & C28 shown in TR1329.pdf for?

Am I right with my guess that they are just for stabilization?

If you have any other helpfull documents refered to the TJA1100 please let me now.

Thanks in advance.

Hi Jerome,

Those capacitors are needed for external buffering of the LDO to stabilize the voltage.

Attached you can find the application hints for TJA1100 for your reference.
