Lm334 constant current

[dimoune]

Hi,

I'm using LM334 as a constant current regulator to control current between 0ma to 10ma. I have a 30v power supply. Do I need to put resistor between the power supply and the +ve of lm334 to protect the regulator or keep it stable? I'm sorry if I did not phrase my question correctly. I'm novice in electornics. Thanks.

The datasheet says the '334 is rated for 40V beween V+ and V-, so you should be ok without a resistor.

Thanks for your confirmation.
