LM2904B: Short circuit 20mA

Jeff Xie

Part Number: LM2904B

Hi team,

Customer want to use LM2904B for 20mA current source power, output near 0V, supply 15V.

Can LM2904B do it? Thanks.

Hi Jeff,

only just at 25°C, but not at other temperatures:

Jeff,

For sinking current, only 5mA is supported. Can you tell me more about the load characteristics and the load termination voltage (is it 15V)

If load current only flows in one direction then a helper transistor could be a solution.
