LM117-series of flexible three-pin positive voltage regulators are capable of providing, in excess of, 1.5 A more than a 1.25 V to 37 V output and a broad temperature range. They ´ re extremely simple to use and require only two external resistors to set the output voltage. Additionally, both line and load regulation are better than standard fixed regulators.
The LM117-series provides full overload protection such as current limit, thermal overload protection, and safe area protection.
No capacitors are needed unless the unit is located over six inches from the input filter capacitors, in which case an input bypass is needed. An output capacitor may be added to improve transient reaction. The adjustment terminal can be bypassed to reach very-high ripple rejection ratios that are hard to reach with regular, three-terminal regulators.
