The specified maximum capacitive load is for each output. 2. Load regulation is specified for a load change of 0% to 100%. Load regulation for 3.3V output models is ±1.0% max for a load change of 0% to 100%. 3. When measuring cross regulation, the load on one output is varied from 25% to 100% while the other output is held at 100%. 4. Output ripple is measured with a 1.0 µF capacitor connected from the +VOUT to the -VOUT pins for single output units and from each output to common for dual output models. See the typical connection diagram & notes on page 3. 5. Transient recovery is measured to within a 1% error band for a load step change of 75% to 50% to 25%. 6. Operation at no-load will not damage these units. However, they may not meet all specifications. 7. It is recommended that a fuse be used on the input of a power supply for protection.

The recommended values are 2.2 µF/100V for C2 & C3 and 12 µH for L1. These components should be mounted as close to the module as possible. To meet the requirements of EN 61000-4-4 & EN 61000-4-5, an external filter capacitor (C1 in the diagram above) is required. The recommended value for C1 is 330 µF/100V. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed from the +VOUT pin to the -VOUT pin for single output units and from each output to common for dual output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple. The Remote On/Off circuit is referenced to the minus input of the unit (pins 2 & 3). If the On/Off input (pin 1) is connected to the minus input, the unit is shut off. If pin 1 is left open, the unit operates normally.
