Description
The LM117 and LM317-N series of adjustable 3-pin positive voltage regulators are capable of supplying in excess of 1.5 A over a 1.25-V to 37-V output range and a wide temperature range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators.
The LM117 and LM317-N offer full overload protection such as current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.
Typically, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-terminal regulators.

Features

DESCRIPTION
The IP117M Series are three terminal positive adjustable voltage regulators capable of supplying in excess of 0.5A over a 1.25V to 60V output range. These regulators are exceptionally easy to use and require only two external resistors to set the output voltage. In addition to improved line and load regulation, a major feature of the “A” series is the initial output voltage tolerance, which is guaranteed to be less than 1%.
Over full operating conditions, including load, line, and power dissipation, the reference voltage is guaranteed not to vary more than 2%. These devices exhibit current limit, thermal overload protection, and improved power device safe operating area protection, making them essentially indestructible.

FEATURES
• Ouput Voltage Range Adjustable:
   1.25 to 40V For Standard Version
   1.25 to 60V For –HV Version
• 1% Output Voltage Tolerance
   (–A Versions)
• 0.3% Load Regulation
• 0.01% / V Line Regulation
• Complete Series Of Protections:
• Current Limiting
• Thermal Shutdown
• SOA Control
• Also Available In Ceramic SMD1 and
   LCC4 Hermetic Ceramic Surface Mount
   Packages.
