    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
