3-TERMINAL 0.5A POSITIVE

ADJUSTABLE REGULATOR

DESCRIPTION

The UTC LM317M is a 3-terminal adjustable positive voltage

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

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

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

voltage.

FEATURES

*Output Current in Excess of 0.5A

*Output Adjustable Between 1.2V and 37V

*Internal Thermal Overload Protection

*Internal Short Circuit Current Limiting

*Output Transistor Safe Area Compensation

*Floating Operation for High Voltage Applications
