These regulators provide a constant output voltage. This will narrow down the pulses at the base input of the pass transistor. 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.

Since the error voltage to the comparator is near zero, the voltage across R2 is approximately equal to Vref. The resistor R2 shown in the figure is not an external component connected to the IC, but an internal resistor that is built inside the IC during manufacture.

The IC is also enabled with current limiting and thermal shutdown capabilities.

IC Voltage Regulators-with Circuit Diagram – Design & Theory

Voltage regulators are of different types. So the current through resistor R2 is:. The frequency of the square wave is decided by the values of R5 and C3. Because of thermal shutdown and current limiting, devices in the LM series dataasheet almost indestructible. The large ripples produced by the circuit should be eliminated and this requires large sized filter capacitors.

This IC is known for its high efficiency and will clearly replace all 3-terminal linear voltage regulators. The basic switching regulator is designed to work in three configurations. So assuming that you were using a 9v batt then you need only add an on-board SMPS.


This datashest given as input to the positive terminal of the triangle to pulse converter.

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

An adjustable voltage regulator is a kind of regulator whose regulated output voltage can be varied over a range. We have given below the block diagram of a 3 terminal IC based voltage regulator. Multi tap ic chip with verying input voltage from 12 v dc down to 3vdc with option to tap in at a voltage output level to match less than 12 volts and usuable voltage datasheer from this for low drain circuits, Prototype made at Bond university Gold Coast Australia.

Adjustable Voltage Regulator An adjustable voltage regulator is a kind of regulator whose regulated output voltage can be varied datwsheet a range. Thus, the current flowing through the potential divider can be written as. In order to remove this unwanted oscillation, the capacitor C1 has to be placed as shown in the circuit. Since the transistor is cut-off, the only path is through the capacitor.

The only difference is in the polarity of output voltages. The duty cycle of these pulses will determine the output voltage. Previous post Next post.

Thus, this regulator finds its extensive use in personal computers. The load regulation is 0. Though they are chosen for different purposes, they do have a disadvantage of high power dissipation of the series pass transistor.

Dafasheet controlling the duty cycle of the pulse generator, the duty cycle of the input voltage to the LC filter is controlled. The operating voltage f he IC can be varied from volts.


The LM series of adjustable voltage regulators is a complement to the LM series devices. The main reason is because the series pass transistor is used as a Class A power amplifier which is known for its low efficiency and power loss in the form of heat.

A fixed voltage regulator can be a positive voltage regulator or a negative voltage regulator. A popular example is the IC which provides a constant 5 volts output. This causes the series pass transistor to get bulky with a bulkier heat sink. The output pulse will then drive the base of the pass transistor. A simple switching regulator is designed with the mix of circuits that we already know.

A positive voltage datxsheet provides with constant positive output voltage. Thus the output voltage can be written as.

An example of IC based voltage regulator available in market is the popular IC which regulates the output voltage at 5 volts.

As shown in the block diagram above, the built-in reference voltage. Capacitor C2 is sometimes used to improve the transient response of the circuit. The IC is known for its flexibility in design by providing output pins for the collector Pin 6 and emitter Pin 5.

How can i apply the adjustable voltage regulator in pitch indicator panel monitoring panel of the ship datashset Astern — ahead of the ship. Furthermore, there is a maximum input voltage because of excessive power dissipation. Vref drives the non-inverting input of the operational amplifier.
