LM7805

This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. Each of these regulators can deliver up to 1.5 A of output current. The internal current-limiting and thermal-shutdown features of these regulators essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents, and also can be used as the power-pass element in precision regulation.

Building a high-efficiency Class D audio amplifier using MOS

“We will discuss the Class D amplifier and build a hardware prototype of the amplifier and test its performance. Audio technology has undergone remarkable evolution in recent decades, reshaping how we consume digital media. From classic tube amplifiers to modern …

PWM Temperature Controlled FAN using TC648 and NTC sensor

“The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The …
