LM317M Description

Short technical summary and product information.

The LM317M and LM317MQ are adjustable floating positive-voltage regulators from SLKOR, capable of supplying an output current of up to 500mA over an output voltage range of 1.25V to 37V. These regulators require only two external resistors to set the output voltage and feature built-in short-circuit current limiting and thermal overload protection.

The device operates with a junction temperature range of -40°C to +125°C. It is available in two package types: a 4-pin SOT-223 measuring 6.5mm x 7mm, and a 3-pin TO-252 measuring 6.6mm x 10.11mm. The SOT-223 package has a thermal resistance of 77.7°C/W, while the TO-252 package offers a lower thermal resistance of 31.7°C/W.

Key electrical characteristics include a typical line regulation of 0.01% and a typical load regulation of 0.1%. The LM317M is designed for stable operation without an output capacitor, though one can be optionally added to improve transient performance. The ADJUST pin can be bypassed with a capacitor for high ripple-rejection ratios.

Applications for the LM317M include cordless vacuum cleaners, building security gateways, multifunction printers, and onboard charging systems.
