Hello,
Currently I'm working on the LDO reg. PSpice macromodel but I have some concerns about the output noise modelling.
After studying some papers on Op-Amp macromodels I was able to obtain fairly good match between the Output Voltage Noise Density Measurements and Simulations in 10Hz-1MHz...
Hi,
Maybe you could use NCP698 - 2.5uA quiescent current LDO from ON Semiconductor. These devices operate with Vin up to 6V and Vout from 1.3V to 5V

I know that TI has also some 1uA LDOs in their portfolio
Best Regards
