Note 1: This value depends on the output voltage.
(It is a value of Vout=3V device. The value of details is described to individual specifications. )
Note 2:The output current is limited by the power dissipation of the total of both sides
.
Parameters with only typical values are just reference. (Not guaranty)
General Note: Limits are guaranteed by production testing or correction techniques using Statistical Quality Control (SQC)
methods. Unless otherwise noted. Vtest=VoutTyp+1vGIL=1mAiTj=25 j
The operation of -30-80 is
guaranteed in the design by a usual inspection.
General Note: Exceeding the “Absolute Maximum Rating “ may damage the device
General Note: Ripple rejection is approximately 84dB
