The opening part of a long series designing a lab power supply from scratch, pointed to as an introduction to voltage regulation, current limiting and op-amp stability.
Linked as the standard explanation of the transistor capacitance multiplier for removing supply ripple, and for its bench demonstration that regulators may reject ripple poorly at higher frequencies.
An Afrotechmods tutorial on building a variable linear power supply around the LM317, often suggested as a first analogue project.
Praised as a hands-on comparison of switching and linear regulators, showing where each is more efficient and helping people decide what to use for battery projects.
Shows a simple LM317 constant current circuit, offered as a cheap way to drive LEDs, though its fitness for laser diodes gets questioned.
A favoured guide to building a bipolar supply from an AC wall adaptor and linear regulators, especially for synth modules and op-amp circuits that need positive and negative rails.
Opening video of a power supply series that explains transformers before later parts cover rectifiers and regulators, recommended to beginners building a first linear supply.
Dave Jones of EEVblog contrasts the two main regulator approaches, a long-standing suggestion for anyone weighing efficiency or first learning how switchers work.
Recommended for working through the sums when adding external transistors to an LM317, so it can supply more current than the chip manages alone.
