LM317M 3-TERMINAL ADJUSTABLE REGULATOR www.ti.com SLVS297M – APRIL 2000 – REVISED OCTOBER 2005 FEATURES Output Voltage Range Adjustable From 1.25 V to 37 V Output Current Greater Than 500 mA Internal Short-Circuit Current Limiting Thermal-Overload Protection Output Safe-Area Compensation Q Devices Meet Automotive Performance Requirements Customer-Specific Configuration Control Can Be Supported for Q Devices Along With Major-Change Approval OUTPUT KTP PACKAGE (TOP VIEW) INPUT ADJUST DCY PACKAGE (TOP VIEW) INPUT OUTPUT OUTPUT ADJUST DESCRIPTION/ORDERING INFORMATION 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 voltage. Furthermore, both line and load regulation are better than standard fixed regulators. In addition to having higher performance than fixed regulators, the device 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. Normally, no capacitors are needed unless the device is more than six inches from the input filter capacitors, in which case an input bypass capacitor is needed. An optional output capacitor can be added to improve transient response. The ADJUST terminal can be bypassed to achieve high ripple-rejection rat……
