Other Parts Discussed in Thread: TPS7A85A
Hi
I have been given a design requirement of a PSRR of 60dB@1KHz. However, the datasheet indicates up to 7% line regulations in the low load range which is probably even worse at 1KHz do to the LC resonance at 6KHz (15uH, 47uF).
What do you think about the 60dB@1KHz requirement using the LM60440 (A or D) webbench design? and please elaborate on how you translate the PSRR to LM60440 spec in case you do not agree with my rough estimation from above.
