Hello team,
My customer woudl like to select the output capacitor(47uF) and they think that they should consider ESR for Cout selection because "High-ESR capacitors may degrade PSRR and affect stability." is written in the datasheet (Page 16)
They have some questions about the relation of Power-Supply Rejection Ratio vs ESR of COUT, and test condition about PSRR (Figure 14. Power-Supply Rejection Ratio vs COUT). Would you please advise?
1) Are there any data of Power-Supply Rejection Ratio vs ESR of COUT?
2) What is type number (or ESR) of Cout (10uF, 22uF, 47uF and 100uF) for PSRR test of Figure 14. Power-Supply Rejection Ratio vs COUT?
3) Would you share the schematics for PSRR test ? What is Vin voltage? What is Vout voltage?
Your advice would be so appreciated.
Best Regards,
Akihisa Tamazaki
