The LM317M is exceptionally easy to use and requires only two external resistors to set the output. Furthermore, both line and load regulation are better than standard fixed regulators. In addition to having higher performance than fixed regulators, the LM317M includes on-chip current limiting, thermal-overload protection, and safeoperating-area protection. All overload protection remains fully functional if the ADJUST terminal is disconnected. The LM317 is a floating regulator meaning there is no device ground terminal. Quiescent current flows to the load instead of being wasted flowing to ground. Regulated output voltage of hundreds of volts i...
