SPECIFICATION NOTES
1) All specifications typical @ 25°C, Nominal Line & Load, unless otherwise
noted.
2) O/P noise measured directly at pins/terminals with 0.1uFbypass, pk-pk @
20MHz bandwidth.
3) Ripple and Noise dependant upon output voltage as specified per particular
model.
4) These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed or implied.
5) Isolation for up to 1 minute duration.
6) No termination necessary with control pin to maintain constant “ON” operation
(if applicable to this model)
7) Max load (peak) specified for 10mS max, 20% duty cycle, minimum load on
all outputs
