5 Output Ripple & Noise Measurement Method
The standard measurement for output ripple and noise are
based on normal probe with 20MHz bandwidth scope.
Upon measurement of the ripple voltage, make sure that
the oscilloscope probe leads are not too long.
Specification
The ripple & noise specification for operating range be-
tween –40℃ to 100℃ is shown below.
i）5.0V & 3.3V
ii）2.5V & 1.8V
iii） JEITA measurement method
Below results are for reference only which is based on
JEITA standard (JEITA probe with 100MHz bandwidth
scope). The measurement condition is Vin=24V and
Tbp=25℃ .
iii) Vo1 (3.3V): output adjust up
iv) Vo2 (2.5V): output adjust up
