4 Maximum Ripple and Noise
The standard measurement for output ripple and noise is
as shown in Fig.4-1. Connect a 22μF ceramic capacitor
for each output (C2 and C3) at 50mm away from the out-
put terminal. Use a normal probe with 20MHz bandwidth
scope to measure the ripple and noise at the position of
C2 and C3. Upon measurement of the ripple voltage,
make sure that the oscilloscope probe leads are not too
long.
Take note that output ripple voltage and output spike noise
may vary depending on PCB wiring design. Generally, out-
put ripple voltage and output spike noise can be reduced
by increasing value of external capacitor.
