LM317EMP
LM117 / LM317A / LM317 -N三端可调稳压器 LM117/LM317A/LM317-N 3-Terminal Adjustable Regulator
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
