Notes:

1. The RP20 F-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. Simulated source impendance of 12uH, 12uH inductor in series with +Vin.

3. The ON/OFF control function. There is positiv logic (standard) and negative logic (option).

The pin voltage is referenced to negative input. To order negative logic ON-OFF control

add the suffix ‘N’ (Ex: RP20-2405SFN)

4. Heat sink is optional and P/N: 7G-0020A. Thermal impedance is 10°C/Watt for natural

convection

5. Maximum value at nominal input voltage and full load.

6. Typical value at nominal input voltage and full load.
