Hello
First, I must let you know that I am fairly new to electronics circuits so please have patience with seemingly simple or stupid questions/comments. I have been reading the data sheet on a 3A 5V regulator, MC78T05, and found that I could use it as a current regulator. This setup might help me lower the power requirements for a circuit I have.
I am currently using primitive voltage/current divider circuits to control my power requirements. I have need of 5V @ 1.5A and so my questions about this regulator configuration (see picture) are:
What exactly is meant by 'output voltage compliance'? That is, what is this 'input voltage less 7.0V'? Does this mean that if I supply 5V that my output voltage will be -2V? How is this value calculated?
I have looked through the data sheet and did not find an equivalent circuit to try to figure out and so I don't know how this is calculated or how it will change for different regulating resistors. Thanks.
