Hi
Has anyone experience with the LM317L/LM337L used as a CCS? I would be interested how this compares regarding impedance to a two-transistor CCS (for reference look i.e. at [removed], Q6 and Q7) and regarding tempco to a LED-biased CCS.
What about noise? Suitable for low-noise work?
I'm aware that using a voltage regulator will result in a highish drop-out voltage.
Thanks for input!
