    Thanks for response Ryan regarding the 15k resistors. Now how are the sense resistors calculated? along with the resistors at the input of the op amp? I know for the TIDA-01232, the document gives us the formula for calculating the ballast resistors…

    Hi Itoh-san, My fault i missed the current sharing part of the first question. Yes you can achieve this through current sharing. You will need to use ballast resistors or amplifiers though. There is a good app note below on how to use ballast resistors…

    Hi Vinnie, Thanks for providing the additional details. Since the LDOs on this device do not have an accessible FB pin, the only way to potentially parallel two LDO1 outputs is to use ballast resistors. This reference design shows an example with a different…
