Hi LDO team!
I am looking for an understanding of the PSRR graph for 3.3Vin, 1.8Vout, at 300mA with 2.2uF cout. The datasheet does a great job of showing a wide variety of PSRR plots. Do we have a tool or method to determine the PSRR for the above conditions?
From figure 28 in the datasheet, I see that for a similar load with a 1.0V dropout, I can expect to always be >38dB (until a few MHz). Is there a way to estimate for a 50% higher dropout what the PSRR will look like?
