Description

The LM317 adjustable positive voltage regulator is capable of supplying more than 1.5A over a 1.2V to 37V output range. They are effortless to use and require only two external resistors to set the output voltage. Further, both line and load regulations are better than standard fixed regulators.

Besides replacing fixed regulators, the LM317 is useful in various other applications. Since the regulator is “floating” and sees only the input to output voltage differential, supplied of several hundred volts can be regulated as long as the maximum input to output voltage differential (of 40V) is not exceeded (i.e. avoid short-circuiting the output).

The LM317 offers complete overload protection. Included on the chip are the current limit and thermal overload protection.

The LM317T is a popular linear voltage regulator integrated circuit (IC) that provides a constant output voltage over a wide range of input voltages. It is commonly used to regulate and control the voltage in electronic circuits.

The LM317T is part of the LM317 series of voltage regulators manufactured by various semiconductor companies. It is a three-terminal device with an adjustable output voltage, and it can handle a maximum input voltage of up to 40 volts. The “T” in LM317T indicates the TO-220 package type, which is a common package for power semiconductors.

The key feature of the LM317T is its ability to provide a regulated output voltage that can be adjusted by external resistors. By connecting two resistors, R1 and R2, to the appropriate pins of the LM317T, you can set the desired output voltage. The formula to calculate the output voltage is:

Vout = 1.25 * (1 + R2/R1)

The LM317T also includes internal circuitry for thermal shutdown, current limiting, and safe operating area protection. These features help protect the IC and the connected circuitry from damage due to excessive current or temperature.

The LM317T is commonly used in a wide range of applications, including power supplies, battery chargers, adjustable voltage regulators, and constant current sources. Its simplicity, ease of use, and availability make it a popular choice for many electronics projects.
