In this circuit, the value of Vref is the reference voltage between the adjustment terminals and the output taken as 1. In order to remove this unwanted oscillation, the capacitor C1 has to be placed as shown in the circuit. The output of the LC filter is a dc voltage with only a small ripple.

We have given below the block diagram of a 3 terminal IC based voltage regulator. The output voltage that is required can be calculated using the equation:.

During each cycle of the pulse the transistor changes between saturation and cut-off. All these problems can be solved by using a switching voltage regulator.

LM is an example of negative adjustable voltage regulator. Thus the current keeps flowing in the same direction.

Here, the series pass transistor is not used as an amplifier, but as a switch. A common type of classification is 3 terminal voltage regulator and 5 or multi terminal voltage regulator.


It is an integrated circuit whose basic purpose is to regulate the unregulated input voltage definitely over a predefined datashheet and provide with a constant, regulated output voltage.

According to the type of use of the IC, an external current limit terminal may be referenced to either the Ground terminal Pin 4 or the the Vin terminal Pin 8. Right now we shall discuss how an LM adjustable positive voltage regulator IC is connected.

Thus, the power dissipation is lessened and thus can carry heavy load currents at low voltages with less bulky heat sinks. The duty cycle of these pulses will determine the output voltage.

This rise in temperature may mostly be due to excessive vatasheet voltage, ambient temperature, or even heat sinking.

The LM A IC was also developed by National Semiconductors and is used as a switching regulator for datahseet like dc-dc voltage converters, inverting configurations and buck-boost converters. An adjustable voltage regulator 34166r a kind of regulator whose regulated output voltage can be varied over a range.


The output pulse will then drive the base of the pass transistor. There are two variations of the same; known as positive adjustable voltage regulator and negative adjustable regulator. So the current through resistor R2 is:. The series pass resistor will have to carry a heavy load when the load current increases.

The IC is also enabled with current limiting and thermal shutdown capabilities. An IC based voltage regulator can be classified in datassheet ways. Adjustable Voltage Regulator using LM Any device in the LM series needs a minimum input voltage at least 2 to 3 V greater than the regulated output voltage.

A voltage regulator is one of the most widely used electronic circuitry in any device. This in turn increases the overall cost as well.
