LM317EMP Datasheet PDF - TI

Description

●The LM117 and LM317-N series of adjustable 3-pin positive voltage regulators are capable of supplying in excess of 1.5 A over a 1.25-V to 37-V output range and a wide temperature 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
