hello,
can anyone tell me
1> what is role of reference voltage in error amplifier design. is it only for operating all transistor in saturation or it has any relation with output of ldo.

my design parameter are:

Vin=0.8-1.8v
Vout=1v
Iload=50mA
Vdo=200mv
technology=0.18um tsmc technology
 

Reference voltage is for correcting error in your desired output by sensing the output voltage.
