Hello team,
Could you please advise with the design team what the purpose of C22 (loop capacitor) in the schema below (CODE IDENTITY NUMBER 01295)?
according to the LDO eval board, this capacitor is not implemented.
Thanks in advance

Hi Shai,
That capacitor is typically called a feedforward capacitor. It is not required but can be included to improve stability, noise, and PSRR. There is more information about the pros and cons of using a feedforward capacitor in this application report:
