“As somewhat of a continuation of my last blog topic I am once again returning to measurement of an LDO parameter as I look at the power supply rejection ratio (PSRR) of this device. As I have been transitioning into this new role I have found that products going into space require much more stringent specifications and review than typical commercial products. Hence, I have found myself evaluating in depth what I always considered a pretty simple device, an LDO. As it turns out I have found out that I was quite the novice with this type of device, hence the title of this blog and my last blog Measuring LDO Noise Spectral Density for a Novice. There are many additional things to think about when working with space products that aren’t necessary to consider for commercial products. I mentioned last time that one of these things is the harsh radiation environments that are present in space…”
