I am mainly interested to know the application of 0V output from a lab power supply. Which linear regulator IC one can use to get 0V output?
Edit:The LT3080 datasheet says that it is adjustable to 0V. How is it useful?
As far as I know, the well-known linear regulator LM317 can output as low as 1.25V but nothing less. However, this page 0 – 24 Volt, 2 Amp Bench Top Power Supply shows a linear power supply circuit that uses LM317 which can output 0V. Is it true?
