LM317S/NOPB Datasheet

Voltage Regulators - Standard


The LM317S/NOPB series of adjustable 3-terminal positive voltage regulators 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. Also, the LM117 is packaged in standard transistor packages which are easily mounted and handled. LM317S/NOPB Features • Specified 1% Output Voltage Tolerance (LM317A)• Specified max. 0.01%/V Line Regulation (LM317A)• Specified max. 0.3% Load Regulation (LM117)• Specified 1.5A Output Current• Adjustable Output Down to 1.2V• Current Limit Constant with Temperature• Output is Short-Circuit Protected
