The TPS766xx data sheet includes some typos concerning output capacitance. Please reitterate the Cout requirements and in particular comment on the ESR requirement for larger capacitors. It appears from the data sheet curves that the requirement is really that the ESR zero be less than 320KHz. Is this correct?
Incorrect wording from data sheet: "The minimum recommended capacitance value is 4.7 mF and the ESR (equivalent series resistance) must be between 300 mW and 20 Ω."
My customer would like to use a 100uF, .022 ohm cap. This would place the ESR zero at 72KHz, which I believe should be OK.
