Is an example for positive adjustable voltage regulator?

LM317 is a classic example of positive adjustable voltage regulator, whose output voltage can be varied over a range of 1.2 volts to 57 volts. In this circuit, the value of Vref is the reference voltage between the adjustment terminals and the output taken as 1.25 Volt.

How do I choose a voltage regulator?

Consider these factors when selecting a voltage regulator:

1. Input Voltage and Output Voltage. Ideally, you know the input voltage range and the required output voltage that you will be working with.
2. Dropout Voltage.
3. Linear Regular or Switching Regulator?
4. Device Sensitivity.
5. Response Time.
6. Power Draw.

What is positive voltage regulator?

The 78xx line are positive voltage regulators: they produce a voltage that is positive relative to a common ground. 78xx and 79xx ICs can be used in combination to provide positive and negative supply voltages in the same circuit.

Which is a three terminal negative voltage regulator IC?

IC 79xx is a three-pin negative voltage controller IC. It is a small integrated circuit used in a circuit to supply a constant negative input voltage.

What is LM317 3-terminal adjustable voltage regulator?

In Depth Guide: LM317 3-Terminal Adjustable voltage Regulator LM317 is a positive-voltage regulator with an adjustable voltage range from 1.25 V to 37 V. It can supply greater than 1.5 A at the output. In most of the applications, due to irregular loads, the output voltage produced has fluctuations in it which can lead to damaging loads.

What are the different types of adjustable voltage regulators?

This adjustable voltage regulator is available in different pin layouts such as LM317L, LM317K, and LM317T. These diagrams show the pinout of all types. However, the functionality of all pins is the same for each type. It is 3 terminal device used for linear regulation of the output. The details of pins are as under:

What is the function of a 3-pin output regulator?

It is 3 terminal device used for linear regulation of the output. The details of pins are as under: Pin1 is an adjustable pin which is used to adjust the output voltage.
