Description

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
Features
• Typ. 0.1% Load Regulation
• Typ. 0.01%/V Line Regulation
• 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
• −55°C to 150°C Operating Temperature Range (LM117)
Applications
• Automotive LED Lighting
• Battery Chargers
• Post Regulation for Switching Supplies
• Constant Current Regulators
• Microprocessor Supplies
