I have switched to a different engine and it needs a 9v battery.

MC34166T Datasheet

The IC has a series pass transistor that can handle more than 1. A positive voltage regulator provides with constant positive output voltage. When the output voltage increases, the comparator circuit produces a higher output voltage and thus the inverting input of the triangle to pulse converter will have high value. During each cycle of the pulse the transistor changes between saturation and cut-off. A common type of classification is 3 terminal 334166t regulator and 5 or multi terminal voltage regulator.

That is, instead of the transistor working in the active region, it is made to switch between the saturation region or cut-off region.

T Datasheet, PDF – Alldatasheet

Now lets come to the basic definition of an IC voltage regulator. The value of Iadj will be very small and will also have a constant value. Their circuit diagrams and explanation are given below. The output pulse will then datasehet the base of the pass transistor. When the transistor switches to cut-off a large voltage will be induced across the inductor coil because of datasehet sudden collapse of the magnetic field around it.

This is given as input to the positive terminal of the triangle to pulse converter. 3416t6 happens should the output voltage fall. By controlling the duty cycle of the pulse generator, the duty cycle of the input voltage to the LC filter is controlled. Pins 1, 2, and 3 are the input, output and ground. The IC is also enabled with current limiting and thermal shutdown capabilities.


A simple voltage divider is used to sample the output of the LC filter. A popular example is the IC which provides a constant 5 volts output.

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

The datasheet rejection is 80 db, equivalent to 10, The ac components of the input voltage to the filter is blocked and the dc component is allowed to pass through the filter. The working starts with the relaxation oscillator which generates a square wave.

Though they are chosen for different purposes, they do have a disadvantage of high power dissipation of datasheer series pass transistor. Otherwise, it will stop regulating. Since the transistor is cut-off, the only path is through the capacitor.

Capacitor C2 is sometimes used to improve the transient response 34166f the circuit. Using 12vdc supply… Can u send me the diagrams for this… Tnx n advance…. This IC is known for its high efficiency and will clearly replace all 3-terminal linear voltage regulators. An adjustable voltage regulator is a kind of regulator whose regulated output voltage can be varied over a range.

This in turn increases the overall cost as well. This creates a rectangular voltage at the input to LC filter. I would also need to be able to switch back to 12v to launch the other engines as needed. Switching Voltage Regulator — Types.

Right now we shall discuss how an LM adjustable positive voltage regulator IC is connected. Thermal shutdown is a feature datashwet will turn off the IC as soon as the internal temperature of the IC rises above datasneet preset value. Furthermore, there is a maximum input voltage because of excessive power dissipation.


The IC is known for its flexibility in design by providing output pins for datashwet collector Pin 6 and emitter Pin 5. This shows that the output of the regulator can be controlled by putting desired values for R1 and R2.

IC Voltage Regulators-with Circuit Diagram – Design & Theory

LM switching voltage regulator circuit diagram is given below. The resistors R1 and R2 determine the output voltage Vout. Adjustable Voltage Regulator An adjustable voltage regulator is a kind of regulator whose regulated output voltage can be varied over a range.

Polarity Inverting Switching Regulatory As shown in the figure above, when the transistor is saturated, the current flows through the inductor. The duty cycle of these pulses will determine the output voltage.

Your email address will not be published. The output voltage that is required can be calculated datashset the equation:. The resistor R2 is adjusted to get the output voltage range between 1. Since the error voltage to the comparator is near zero, the voltage across R2 is approximately equal to Vref.

The high efficiency of the IC can be obtained even without a heat sink.

An IC based voltage regulator can be classified in different ways. The basic switching regulator is designed to work in three configurations. A fixed voltage regulator can be a datashest voltage regulator or a negative voltage regulator. The series pass resistor will have to carry a heavy load when the load current increases.

There may be certain conditions where a variable voltage may be required. In the above equation, due to the small datashedt of Iadj, the drop due to R2 is neglected.

Thus the current keeps flowing in the same direction.
