The simplest of fan-control schemes — an on-off switch — is simple but inefficient, because it provides more cooling than necessary most of the time. When on, the fully powered switch-controlled fan ...
In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...
Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...
