Raa214035 bode plot

Question

Hi 
 We are using the RAA214035 LDO for 0.8V output voltage at our board, we want to test the bode plot from output to control, but we can not get the correct bode plot waveform. can you advise if RAA214035 can do a bode plot test and how to do the correct bode plot test?Thanks!

Hi, 
 The RAA214035 does not offer access to the internal control loop between the error amplifier and the pass element, which is typically required to perform a direct Bode plot measurement (such as loop gain or phase margin analysis) using a network analyzer.
