In the present,I have confused with the problem.Generally,how many poles and zero in LDO IC with bipolar process? which is the dominant pole? and which part do each of them come from? Are they diffrent from with CMOS LDO?thanks very much! Below picture show the block of LDO

怎么看不到图？

I agree that it seems the circuits will be more easy to understand if replace Q1 with a NPN.
Right, master?

what are the differences between bjt and cmos? Are they necessary to be large to conduct same amount of currents? And what are the output resistances for bjt and cmos? I think the differences exist in the answers to these questions.
