Detailed Solution
Download Solution PDFVoltage Regulator:
It is an electronic circuit that gives a smooth output voltage. Smooth voltages are most important for the working of digital circuits.
An IC-based voltage regulator can be classified in different ways.
The 3 terminal IC voltage regulator block diagram is shown below:
- IC linear voltage regulators use an active pass element to reduce the input voltage to a regulated output voltage.
- IC switching voltage regulators store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.
- DC/DC converter chips, the third type of IC voltage regulators, also provide a regulated DC voltage output from a different, unregulated input voltage.
Conclusion: In a linear IC voltage regulator, the series pass transistor always operates in the active region.
