What does an adjustable voltage regulator do?
An adjustable voltage regulator produces a DC output voltage, which can be adjusted to any other value of certain voltage range. Hence, adjustable voltage regulator is also called as a variable voltage regulator. The DC output voltage value of an adjustable voltage regulator can be either positive or negative.
Which is an adjustable positive voltage regulator?
The LM317T is an adjustable 3-terminal positive voltage regulator capable of supplying different DC voltage outputs other than the fixed voltage power supply of +5 or +12 volts, or as a variable output voltage from a few volts up to some maximum value all with currents of about 1.5 amperes.
What is difference between fixed and adjustable voltage regulator?
Adjustable Voltage regulators require a very few external components to achieve its operation. Fixed voltage regulators require almost no external components (may be a couple of bypass capacitors). At low cost you have a wide range of voltage and current selection.
Which of the 2 types of voltage regulator is better to use?
The most affordable and often the easiest type of voltage regulators to use are linear voltage regulators. Linear regulators are compact and often used in low-voltage, low-power systems. Switching regulators are more efficient than linear voltage regulators, but are harder to work with and are more expensive.
How do you increase the current level of a 723 regulator?
The 723 voltage regulator is commonly used for series voltage regulator applications. It can be used as both positive and negative voltage regulator. It has an ability to provide up to 150 mA of current to the load, but this can be increased more than 10A by using power transistors.
What are the difference between linear voltage regulator and adjustable voltage regulator?
As its name suggests, a linear regulator is one where a linear component (such as a resistive load) is used to regulate the output….Linear Regulator.
