Line Regulation, Single Output ............... 0.2% (From Low line to High Line)
Line Regulation, Dual Output.................. 0.2% -V to +V (From Low line to High Line)
0.4% -V or +V to common
Load Regulation, Single Output .............. 1.0% Max for output current changes between
10% and 100% of full load.
Load Regulation, Dual Output................. 1.0% Max -V to +V for output current changes between
10% and 100% of full load.
2.0% -V or +V to common for output current changes
between 10% and 100% of full load.
Cross Regulation ..................................... Dual output models: Current change from 10% to 100%
of full load on positive output will result in less than 3.0%
(Max.) change in the negative output voltage.
(Note:
Ripple and noise specifications are differential mode, and measured at the output
terminals of the converter utilizing the EIAJ method. All specifications reflect a 20 Mhz.

Ripple and Noise, Single Output ............. 3.3, 5.0 volt outputs: 75 mVp-p
12 volt outputs: 100 mVp-p
15 volt outputs: 100 mVp-p
Ripple and Noise, Dual Output................ 100 mVp-p
Remote Resistance Programming ............ "TRIM" pin is available which allows ± 10%
adjustment of main output voltage via addition of external
resistor referenced to either +V or -V terminal.
Remote Voltage Programming ................ All units can be remotely programmed from an external
voltage source by utilizing the "Trim" pin
Temperature Coefficient.......................... ± 0.015% per oC, maximum. (measured on center of case)
Output Voltage Drift ............................... 0.3% maximum over 8 hour period on main output
(after thermal equilibrium is reached)
Initial Set Point, Single Output................ ± 1.0%
Initial Set Point, Dual Output .................. ± 1.0% -V to +V
Output voltage balance at full load: The difference between
+V to common and -V to common should be less then
±2%
of
+V to -V.
