similar way, the negative feedback circuit increases VCEto ensure the accurate regulation of the 3.3V output. In summary, any variation of VOis absorbed by the linear regulator transistor’s VCEvoltage. So the output voltage VCCis always constant and well regulated. Figure 3. A Linear Regulator...
Power supplies are among the most popular topics in electronics. There are two major types of regulated power supplies: linear and switching. Both power supply types introduce some advantages and disadvantages. However, a linear power supply offers better line and load regulation figures and it hand...

The series voltage regulator or as it is sometimes called the series pass regulator is the most commonly used circuit design approach for providing the final voltage regulation in a linear regulated power supply. The series linear voltage regulator provides a high level of performance, espec...
If the IC has a fixed voltage regulator, the Vin pin can be used to power it, and the Vout pin can be used to get the regulated output. The Adj/Ground pin is only used as a ground pin in this scenario and is grounded. To filter out noise, a capacitor can...

The output is regulated by controlling the voltage drop across the series-pass element, a power transi...
As a leading-edge modulator; a mag amp is particularly beneficial in current mode regulated power supplies as it insures that no matter how the individual output loading varies, the maximum peak current, as seen in the primary, always occurs as the pulse is terminated. Mag Amp Operation ...
