The LM317L3 is an adjustable 3–terminal positive
voltage regulator capable of supplying in excess of 1.5A 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 LM317L3 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 LM317L3 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 ● Eliminates Stocking many Fixed
Voltages ● Pb-free lead plating and halogen-free package.

*Cin is required if regulator is located an appreciate distance from power supply filter.
**Cout is not needed for stability, however, it does improve transient response.
