Editor's note: Designers at all levels of power management design will find this application article both educational for those not very familiar with these basic concepts as well as an excellent ...

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 ...

We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. Linear regulators are imperfect, of ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) The linear voltage regulator was introduced in Part 11 of this series (link below).

Two basic IC topologies are employed in dc power sources. If the output is lower than the input voltage, the IC is said to be a step-down, or buck converter. If the output is higher than the input ...
