INTRODUCTION
Standard positive (LM317) and negative (LM337) three terminal regulators (TTRs), are dead convenient for making fixed and variable voltage power supplies to provide between 50mA and 7A, but, generally, they do not go lower than their 2.25V, floating reference voltage.

You can get around this by using one of the reference current regulators like the Linear...
