Description: LM317T Voltage Regulator IC Linear Voltage Stabilizer Adjustable Voltage Regulator LM317 37V 1.5A TO-220 Package 3 Pin LM 317 IC

LM317 variable voltage regulators. STMicroelectronics manufacturer’s part number LM317T. The output voltage is adjustable between positive 1.2 to 37 V. The output current varies between 2.2A for Vin-Vout ≤ 15V and 400mA at Vin-Vout = 40V.

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

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

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

TheLM317Tis a popular variable voltage regulator that is used in power regulation circuits by hobbyists and professionals alike. The output voltage of LM317 can be adjusted from 1.2V to 37V with a maximum output current rating of 1.5A. The IC is commonly used for voltage regulation and current regulation circuits in chargers and other power modules.It comes in a breadboard friendly TO220 package and required very simple external components, few resistors, and a capacitor to operate as a function circuit.It can be used in positive voltage regulator circuits, Variable Power Circuits like battery chargers, and are commonly used in Desktop PC, DVDs, and other consumer products.
