hello friends,
i am designing an ldo .
can any help me how to plot variation of output voltages with variation in load current in tanner?
if i want to check the stability of ldo. how i have to perform dc analysis for it ?...just simply by selection out put port and input port and make dc analysis am i right?
 

1. Put a fixed VDC source at the LDO input
2. Put an IDC source (as current load, with any reasonable current) at the output
3. Call a DC analysis and sweep the IDC output current
4. Run the DC analysis
5. Plot the output voltage vs. output current
