Specification
General specifications apply for the temperature range 5°C to 40°C. Accuracy specifications
apply for the temperature range 18°C to 28°C after 1 hour warm-up with no load and calibration at
23°C. Typical specifications are determined by design and are not guaranteed.

Ripple and Noise
(20MHz bandwidth):
Normal mode voltage: <0·35mVrms and 2mVp-p
Normal mode current: <0·2mArms; <20
µ
Arms on 500mA range.
Load Regulation:
For any load change, measured at the output terminals, using
remote sense.
Voltage <0·01% + 2mV.
Current <0·01% + 250µA; <0.01% +50µA on 500mA range.
Add typically 2·5mV for a 0·5V drop in the positive output lead.
Specification applies for sense lead resistance <0·5
Ω
.
Line Regulation:
Voltage <0·01% + 2mV for 10% line change.
Current <0·01% + 250µA; <0.01%+ 50µA on 500mA range.
Temperature Coefficient: Voltage: typically <(50ppm + 0·5mV)/°C
Current: typically <( 1mA)/°C;
( 0·1mA)/°C on 500mA range.
Output Protection:
Output will withstand forward voltages of up to 20V above rated output
voltage. Reverse protection by diode clamp for currents up to 3A.
