ratasheet The series pass resistor will have to carry a heavy load when the load current increases. Thus the current keeps flowing in the same direction. When the output voltage increases, darasheet comparator circuit produces a higher output voltage and thus the inverting input of the triangle to pulse converter will have high value.

This high gain helps the op. An IC based voltage regulator can be classified in different ways. Otherwise, it will stop regulating.

IC Voltage Regulators-with Circuit Diagram – Design & Theory

Step-up Switching Regulator As shown in the figure above, the rectangular pulses datasheett given to the base of the transistor. Voltage regulators are of different types. Oh yes you can, matters would have been easier if you had specified datasheeh required current demand on 9v. The operating voltage f he IC can be varied from volts.

The datasheef of the square wave is decided by the values of R5 and C3. Here, the series pass transistor is not used as an amplifier, but as a datsheet. We have given below the block diagram of a 3 terminal IC based voltage regulator. A simple voltage divider is used to sample the output of the LC filter. Previous post Next post. The functional block diagram of the IC as a switching regulator is shown below. In order to remove this unwanted oscillation, the capacitor C1 has to be placed as shown in the circuit.


The LM A IC was also developed by National Semiconductors and is used as a switching regulator for applications like dc-dc voltage converters, inverting configurations and buck-boost converters. Now lets come to the basic definition of an IC voltage regulator.

The whole operation is completely different when compared to a linear voltage regulator. A positive voltage regulator provides with constant positive output voltage. Try a tiny circuit based on popular smps Ic based circuit. Is there a way to use the rechargeable 12v battery still but only have it put out 9v? There are two variations of the same; known as positive adjustable voltage regulator and negative adjustable regulator.

This rise in temperature may mostly be due to excessive external voltage, ambient temperature, or even heat sinking. When there is quite a distance in cms from the IC to the filter capacitor of the unregulated power supply, there may occur unwanted oscillations within the IC datashewt to lead inductances within the circuit. Vref drives the non-inverting input of the operational amplifier.

The large ripples produced by the circuit should be eliminated and this requires large sized filter capacitors. The connection diagram is shown below.

3A, Step-Up/Down/Inverting Switching Regulator

In this article, our interest is only with IC based voltage regulator. Adjustable Voltage Regulator using LM The resistor R2 is adjusted to get the output voltage range between 1. I would also need to be able to switch back to 12v to launch the other engines as needed.


Because of thermal shutdown and current limiting, devices in the LM series are almost indestructible. The square wave is given as input to the integrator and produces an output triangular wave. The high efficiency of the IC can be obtained even without a heat sink. Such linear regulators will also need a step-down transformer which again increases the size of the overall circuit. This will narrow down the pulses at the base input of the pass transistor.

Capacitor C2 is sometimes used to improve the transient response of the circuit. It is an integrated circuit whose basic purpose 3166t to regulate the unregulated input voltage definitely over a predefined range and provide with a constant, regulated output voltage.

This voltage datasheer then fedback to the comparator circuit where a reference voltage Vref is compared with the output voltage and passed on to the negative input of the triangle to pulse converter.

Furthermore, there is a maximum input voltage because of excessive power dissipation. The load regulation is 0. I am also not an electrician so the easier answer the better. The figure above shows the application of LM IC as a voltage regulator. Thus, the power dissipation is lessened and 344166t can carry heavy load currents at low voltages with less bulky heat sinks.
