The big output capacitor along with output resistance of LDO will be the dominant pole of the system. This makes it easier to compensate compared with one without output capacitor.1)what is the need of a capacitor and why dose he so important in this circuit?
But this circuit is not a LDO type.The big output capacitor along with output resistance of LDO will be the dominant pole of the system
From this page, it is an enhancement of transistor regulator. I think it can be called a type of LDO. The only different I notice is that in LDO the BJT transistor is not a voltage buffer as above. So maybe no compensation is necessary for this.But this circuit is not a LDO type.
