2 EEVBlog #1116 - How to Remove Power Supply Ripple
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.
3 LM317 Adjustable Voltage Regulator Tutorial
An Afrotechmods tutorial on building a variable linear power supply around the LM317, often suggested as a first analogue project.
4 Buck converter vs. linear voltage regulator - practical comparison
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.
5 Constant current power supply and laser / LED driver tutorial
Shows a simple LM317 constant current circuit, offered as a cheap way to drive LEDs, though its fitness for laser diodes gets questioned.
6 What is a Transformer? An Electrical Transformer Tutorial
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.
