LM334 Biasing Voltage Calculation to generate constant current

Ronak Shah
Prodigy 110 points

Hello All,

I am working on Ti LM334Z, to generate constant 2mA current to resistive load (around 2K to 5K, typ 5Kohm).

I have constant battery voltage source of 3.7VDC. I had calculated value for resistors. 

Can anyone support, how to find required Vin+ voltage to generate constant 2mA for 5Kohm. And what are typical calculations?

And If supply 3.7VDC to LM334z, how much maximum constant current, can I generate with 5K ohm load?

Thanks,

Ronak Shah
