Application Note 142 August 2013 Bob Dobkin Regulators regulate but are capable of doing much more. The architecture of linear regulators has remained virtually unchanged since the introduction of the three terminal floating voltage regulator in 1976. Regulators were either a floating architecture LT317 or else an amplifier loop with feedback from the output to the amplifier. Both of these architectures suffer from limitations on versatility, regulation and accuracy. The feedback resistors set ...
