Part Number: LM317

Hi Team,

1. Please provide the soft start value.

2. What is Volreg(min)? How do we interpret this formula?

    Hi Allen,

    1. LM317 does not have an internal soft-start circuit. If soft start is needed, a circuit similar to that shown in Figure 8-13 may be used.

    2. Equation 5 appears to be an error and may be disregarded.

    Best Regards,
