    High-Efficiency Reg has Low Drop-Out Voltage (Rev. B)
    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

    AN-181 3-Terminal Regulator is Adjustable (Rev. B)
    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
