App note: Op-amp based DIY linear voltage regulators

This is not really an app note, but more of a tutorial on DIY op-amp based linear regulators. The article describes the basics of op-amp regulator, and includes schematics and in-depth explanations of how the various circuits work. This article follows the history of a popular series of DIY linear regulators. Starting from initial concepts […]

Partlist Wednesday: Voltage regulators

Every Wednesday we highlight a component from the updated partlist. This week: regulators. This week’s part: voltage regulators. We try to use the cheap 150mA voltage regulators in SOT-23 package whenever possible. These are cheap (from 25 cents in 1s) and super resilient to shorts, over temperature, and over load. 150mA is enough for the […]
