The RP20 series requires a minimum of 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specification. 2. BELLCORE TR-NWT-000332. Case l: 50% Stress, Temperature at 40°C (Ground fixed and controlled environment). 3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin. 4. Maximum value at nominal input voltage and full load of standard type. 5. Typical value at nominal input voltage and full load. 6. Test by minimum Vin and constant resistor load. 7. The ON/OFF control voltage is reference to negative input. 8. Heat sink is optional and P/N: 7G-0011A. Operation temperature range please see curve. 9. Cross regulation: Dual output—Asymmetrical load 25% to 100% full load Triple output – 3.3V / 5V 100% load and one of auxiliary 100% load, other auxiliary load change from 25% to 100% load 10.See application notes for EMI-filtering.
