www.micropowerdirect.com Page 2 We Power Your Success - For Less Model Selection Guide Notes: 1. The specifi ed maximum capacitive load is for each output. 2. Load regulation is specifi ed 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 +V OUT 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 specifi cations. 7. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the correct rating.

The recommended value for C1 & C2 is 330 µF/100V. A single 680 µF/100V capacitor may also be used. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed from the +V OUT pin to the -V OUT 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.
