What is the use of IC LM317?
LM317 Voltage regulator IC It’s an adjustable three-terminal voltage regulator IC, with a high output current value of 1.5A. The LM317 IC helps in current limiting, thermal overload protection and safe operating area protection. It can also provide float operation for High voltage application.
What is the maximum limit of output current of the IC 317?
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 IC regulated power supply?
The IC Regulated power supply (RPS) is one kind of electronic circuit, designed to provide the stable DC voltage of fixed value across load terminals irrespective of load variations. The main function of the regulated power supply is to convert an unregulated alternating current (AC) to a steady direct current (DC).
What is the current rating of voltage regulator IC LM317 L?
The LM317L is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 100 mA over an output voltage range of 1.2 V to 37 V.
What is regulated power supply used for?
A regulated power supply with multiple regulators can offer multiple output voltages for operating different devices. Regulated power supplies maintain the voltage at the desired level and are ideal for almost all types of electronic devices because of the smooth, steady supply of voltage they offer.
How does the LM317 power supply work?
The LM317 IC output is then connected to the signal probe of a voltmeter to display the immediate voltage across any load such as an LED or a DC fan etc. Adjustable Power supplies serve in applications such as powering home appliances, power tools, test bench supplies & trainer board supplies.
What does the 78 mean on the LM317 adjustable regulator?
The 78 represents the series while the last two digits represent the voltage. Although we have this much variety of the voltage regulators then why we need the LM317 adjustable regulator?
Which IC can be used as a variable power supply?
But this circuit can be created with a single IC is lm317 based variable power supply. The LM317 or LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to the 37V output range,
What is the output voltage of the LM317 220V adapter?
A 220V AC wall adapter is used to translate the 220V input AC to a Rectified 24V – 12V DC signal, which is then fed to the Vin terminal of the LM317 using a DC power jack. This three-terminal voltage regulator has an output voltage operating range from 1.2V to 37V DC with a maximum load current of up to 1.5A.
