Fairchild SEMICONDUCTOR RC5051 - Manual (Page 19)

APPLICATION NOTE AN50
19
Note:
Load regulation is expected to be typically around 0.8%. The
load regulation performance for this device under evaluation
is excellent.
Output Voltage Load Transients Due to Load Current Step
This test is performed using Intel P6.0/P6S/P6T Voltage
Transient Tester.
Note:
Transient voltage is recommended to be less than 4% of the
output voltage. The performance of the device under evalua-
tion is significantly better than a typical VRM.
