500 mA Adjustable Output,

Positive Voltage Regulator

The LM317M is an adjustable three−terminal positive voltage

regulator capable of supplying in excess of 500 mA over an output

voltage range of 1.2 V to 37 V. This voltage regulator is exceptionally

easy to use and requires only two external resistors to set the output

voltage. Further, it employs internal current limiting, thermal

shutdown and safe area compensation, making it essentially blow−out

proof.

connected to Pin 2

The LM317M serves a wide variety of applications including local,

on−card regulation. This device also makes an especially simple

adjustable switching regulator, a programmable output regulator, or by

connecting a fixed resistor between the adjustment and output, the

LM317M can be used as a precision current regulator.

ORDERING INFORMATION

See detailed ordering and shipping information in the package

dimensions section on page 10 of this data sheet.

ꢀ* = C is required if regulator is located an appreciable distance from power supply filter.

** = C is not needed for stability, however, it does improve transient response.

DEVICE MARKING INFORMATION
