    Conventional regulators have a high drop-out voltage that is a function of the total output current.However with just a regulator chip an external transistor and a few passive components this designforms a high output current regulator with a limited input voltage and high efficiency. The circuit presentedhas a drop-out of 0.7V at 5A load current and 1.3V at a current level of as high as

    Until now all of the 3-terminal power IC voltage regulators have a fixed output voltage. In spite of this limitation their ease of use low cost and full on-chip overload protection have generated wide acceptance. Now with the introduction of the LM117 it is possible to use a single regulator for any output voltage from 1.2 V to 37 V at 1.5A. Selecting close-tolerance outp
