Product Description

The LM317MQDCYR is a 3-terminal adjustable Positive Voltage Regulator capable of supplying more than 500mA over an output-voltage range of 1.25V to 37V. The LM317M is exceptionally easy to use and requires only two external resistors to set the output. Furthermore, both line and load regulation is better than standard fixed regulators. In addition to having higher performance than fixed regulators, this regulator includes on-chip current limiting, thermal-overload protection and safe- operating-area protection. All overload protection remains fully functional if the ADJUST terminal is disconnected. It 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 40V at any time. Device can be used as a floating current source controlled by a single resistor.

Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
