The IC is known for its flexibility in design by providing output pins for the collector Pin 6 and emitter Pin 5.
A common type of classification is 3 terminal voltage regulator and 5 or multi terminal voltage regulator. A popular example is the IC which provides a constant 5 volts output. The resistor R2 is adjusted to get the output voltage range between 1. It should solve almost all your requirements and is light too. Thus, this regulator finds its extensive use in personal computers. The series pass resistor will have to carry a heavy load when the load current increases.
Step-down Switching Regulator As shown in the figure above, the rectangular pulses are given to the base of the transistor. A simple switching regulator is designed with the mix of circuits that we already know. An adjustable voltage regulator is a kind of regulator whose regulated output voltage can be varied over a range. Switching Voltage Regulator — Types. An example of IC based voltage regulator available in market is the popular IC which regulates the output voltage at 5 volts.
3A, Step-Up/Down/Inverting Switching Regulator
I would also need to be able to switch back to 12v to launch the other engines as needed. Since the duty cycle is lower, the filtered output voltage is less, which tends to cancel almost all the original increase in the output voltage.

Since the transistor is cut-off, the only path is through the capacitor. Capacitor C2 is sometimes used to improve the transient response of the circuit. The LM series of adjustable voltage regulators datashdet a complement to the LM series devices.

The ripple rejection is 80 db, equivalent to 10, Right now we shall discuss how 34166t LM adjustable positive voltage regulator IC is connected. LM switching voltage regulator circuit diagram is given below.
Thus, the power dissipation is lessened and thus can carry heavy load currents at low voltages with less bulky heat sinks. Using 12vdc supply… Can u send me the diagrams for this… Tnx n advance….
In this article, our interest is only with IC based voltage regulator.
There may be certain daatsheet where a variable voltage may be required. Your email address will not be published. Try a tiny circuit based on popular smps Ic based circuit. The resistors R1 and R2 determine the output voltage Vout.

The value of Iadj will be very small and will also have a constant value. An IC based voltage regulator can be classified in different ways.
Because of thermal shutdown and current limiting, devices in the LM series are almost indestructible. It is an integrated circuit whose basic purpose is to regulate the unregulated input voltage definitely over a predefined range and provide with a constant, regulated output voltage.
Furthermore, there is a maximum input voltage because of excessive power dissipation. So the current through resistor R2 is:. By controlling the duty cycle of the pulse generator, the duty datashewt of the input voltage to the LC filter is controlled.
