Description

Description
The LM317A adjustable 3-terminal, positive-voltage regulators are capable of supplying current in excess of 1.5 A over a 1.25-V to 37-V output range and provide 1% output-voltage accuracy. The LM317A device is available in an SOT-223 package, which makes it ideal for space-constrained applications that require high-performance regulation. The device is exceptionally easy to use and requires only two external resistors to set the output voltage. Both line regulation and load regulation are better achieved with the LM317A device than with standard fixed regulators.
Features
• Typical 0.005%/V Line Regulation
• 1% Output Voltage Tolerance
• 1.5-A Output Current
• Adjustable Output Down to 1.25 V
• Current Limit Constant with Temperature
• 80-dB Ripple Rejection
• Short-Circuit Protected Output
• −40°C to 125°C Operating Temperature Range
Applications
• Automotive LED Lighting
• Battery Chargers
• Post Regulation for Switching Supplies
• Constant-Current Regulator
• Microprocessor Supplies
