Texas Instruments LM317M
The LM317M is an adjustable 3-terminal positive voltage regulator capable of supplying more than 500-mA over an output-voltage range of 1.25-V to 37-V. The LM317M is exceptionally easy to use and requires only two external resistors to set the output. In addition to having higher performance than fixed regulators, the LM317M includes on-chip current limiting, thermal-overload protection, and safeoperating-area protection.| Part No. | LM317M |

DESCRIPTION
Furthermore, both line and load regulation are better than standard fixed regulators. 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 is possible if the maximum input to output differential does not exceed 40-V at any time. Device can be used as a floating current source controlled by a single resistor.
