The specified maximum capacitive load is for each output. 2. Cross regulation is measured with the output being tested at 50% load. The second output is varied from 10% to 100% load. 3. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF) be placed from the +VOUT to the -VOUT pins for single output models; or from each output to common for dual output models. 4. Transient recovery is measured to within a 1% error band for a load step change of 25%. 5. Short circuit protection is provided by a “hiccup mode” circuit. 6. These units should not be operated with a load under 5% of full load. Operation at no-load will not damage the unit, but they may not meet all specifications. 7. The maximum control current at the on/off pin (pin 6) during a logic high is 50 µA. The maximum control current to the on/off pin at logic low (-0.7V to 0.8V) is 1 mA. If the on/off pin is left open, the unit operates. If it is grounded, the unit will shut off. 8. It is recommended that a fuse be used on the input of a power supply for protection.
