1.5 A Adjustable Output,

Positive Voltage Regulator

The LM317 is an adjustable 3–terminal positive voltage regulator

capable of supplying in excess of 1.5 A 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.

The LM317 serves a wide variety of applications including local, on

card regulation. This device can also be used to make a programmable

output regulator, or by connecting a fixed resistor between the

adjustment and output, the LM317 can be used as a precision current

regulator.

• Output Current in Excess of 1.5 A

• Output Adjustable between 1.2 V and 37 V

• Internal Thermal Overload Protection

• Internal Short Circuit Current Limiting Constant with Temperature

• Output Transistor Safe–Area Compensation

• Floating Operation for High Voltage Applications

• Available in Surface Mount D2PAK, and Standard 3–Lead Transistor

Package

• Eliminates Stocking many Fixed Voltages

Standard Application

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

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

Since IAdj is controlled to less than 100 µA, the error associated with this term is

negligible in most applications.
