This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

Linear Technology's recently introduced LTC4300 chip buffers I 2 C clock and data lines to and from a hot-swappable card. This task is difficult because the IC must work bidirectionally, meaning that ...
