[Kevin Darrah] wanted to make a simple 3.3V regulator without using an ... and 4 1K resistors. The circuit isn’t going to beat out a cheap linear regulator IC, but for the low component count ...

The first thing I ever built without a ... this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and produces ...

While the required external Ls and Cs (of course) vary wildly from topology to topology and chip to chip, (almost) all use exactly the same basic two-resistor network for output voltage programming ...
