    PDF, 314 Kb, 修订版: B, 档案已发布: May 5, 2013
    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

    Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changingload transients and also bypass very high frequency noise coming from switching converter powersources which a linear regulator can not reject. However using ultra-low ESR capacitors on the output ofan LDO regulator requires that specific design changes be implemented to ensure loop stabili
