hello
could you tell me how to do AC open loop LDO simulation properly?
how the inputs should be polarized when i open the loop to pass device give me the current i want to.
when i do transient and op analyses, everything is ok. vref is connected to - and output voltage through feedback divider to +.
i want the AC simulation to be adequate TRANSIENT simulation, to be sure how gain, UGF and pole/zero position influence transient response
thanks in advance
regards
