( 5 pcs ) LM317T TO220 1,5A Adj. Voltage Regulator

The LM117 series of adjustable 3-terminal positive voltage regulatorsis capable of supplying in excess of 1.5A over a 1.2V to 37V outputrange.
They are exceptionally easy to use and require only two externalresistors to set the output voltage.
Further, both line and load regulation are better than standard fixedregulators.
Also, the LM117 is packaged in standard transistor packages which areeasily mounted and handled.
In addition to higher performance than fixed regulators, the LM117series offers full overload protection available only in IC's.
Included on the chip are current limit, thermal overload protection andsafe area protection.
All overload protection circuitry remains fully functional even if theadjustment terminal is disconnected.
Normally, no capacitors are needed unless the device is situated morethan 6 inches from the input filter capacitors in which case an inputbypass is needed.
An optional output capacitor can be added to improve transientresponse.
The adjustment terminal can be bypassed to achieve very high ripplerejection ratios which are difficult to achieve with standard3-terminal regulators.
Besides replacing fixed regulators, the LM117 is useful in a widevariety of other applications.
Since the regulator is “floating” and sees only the input-to-outputdifferential voltage, supplies of several hundred volts can beregulated as long as the maximum input to output differential is notexceeded, i.e., avoid short-circuiting the output.
Also, it makes an especially simple adjustable switching regulator, aprogrammable output regulator, or by connecting a fixed resistorbetween the adjustment pin and output, the LM117 can be used as aprecision current regulator.
Supplies with electronic shutdown can be achieved by clamping theadjustment terminal to ground which programs the output to 1.2V wheremost loads draw little current.
For applications requiring greater output current, see LM150 series(3A) and LM138 series (5A) data sheets. For the negative complement,see LM137 series data sheet.
