Back to Basics: Voltage Regulator ICs, Part 1

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

Back to Basics: Voltage Regulators, Part 2

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

Basic switching-regulator-layout techniques

When considering how best to lay out a switching-regulator board, it's good to recall its purpose, which is to supply a steady voltage of a specific magnitude. Experienced layout designers achieve ...
