REF200: Load resistance of constant current source

Rhea Gao

Part Number: REF200

Hi，

Would you like to ask, constant current * load resistance < constant current source chip power supply voltage? Or are there any requirements for the load resistance?

Many thanks~

Hello,

There needs to be a margin of compliance voltage between the supply voltage and the output current*load resistance.

Best,

Walter
