Hi,
I'm building a power supply based on lm317/350 voltage regulators and i'm trying to figure out using the datasheet what output voltage regulation/ripple to expect based on the input voltage. The input voltage comes from bridge rectifier and filter caps and i expect about 1.2V p-p ripple on that voltage (50Hz before the rectifier so 100Hz after it) at full load (about 2.5A). The input voltage will be about 34 volts filtered. The output voltage will be 1.25-24V 2.5A max. What parameter should i look for in the datasheet and whats the basic procedure for some rough estimates?
