I am trying to measure load regulation for LDO when the load varies from 0.1mA to 10mA by using 2 resistors one of 1.8k and the other of 180 since the output voltage is 1.8V So i have 2 branches each is on using ideal switch controlled through v(c1),v(c2) respectively i got this curve so is this true to calculate the load regulation by taking the difference between ldo_out at 10u (S1 on S2 off) and at 70u (S2 off S1 on )? What about the abrupt change which occur for very few microseconds is this tolerable since it takes small time or not ?
