Designing a new power step down voltage regulator.
We need a very low noise 5-volt power supply, approx. 20 - 30 uVrms
Input 12 volt (stable) max 2,5A, operating temp range approx. 30ºC 40ºC
I tried to find a regulator in the LDO voltage regulator section, those regulators are not capable to handle above specs.
I tried to make a design with webench tool with the LM3102, UL3836, tps563200DDCR. By simulating those designs, the load transient is too high.
Is it possible to point me in the right direction to make a choice for a good regulator?
