LM1117

700.00

The LM1117 is a low dropout voltage regulator available in fixed and adjustable output versions. It is designed to provide an output current of up to 800mA with a dropout voltage of 1V at full load. This regulator is ideal for various applications, including powering low-voltage digital systems, post-regulation of switching supplies, and battery-powered devices.

Key Features:

  • Low Dropout Voltage: 1V at 800mA
  • Output Current: Up to 800mA
  • Fixed and Adjustable Versions: Output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V
  • Thermal Overload Protection: Protects the regulator from overheating
  • Short Circuit Protection: Protects the regulator and the load
  • High-Accuracy Output Voltage: ±1% (fixed version)
  • Low Quiescent Current: Ideal for battery-powered applications

Technical Specifications:

  • Input Voltage Range: Up to 20V
  • Output Voltage Tolerance: ±1% (fixed version)
  • Dropout Voltage: 1V at 800mA
  • Output Current: 800mA
  • Operating Junction Temperature Range: -40°C to +125°C
  • Package Options: SOT-223, TO-220, and TO-263

Applications:

  • Low voltage digital systems
  • Post-regulation for switching supplies
  • Battery-powered devices
  • Portable instruments
  • Motherboards
  • Powering FPGAs, ASICs, and DSPs

Usage:

  1. Connect the input voltage to the input pin of the LM1117.
  2. Connect the output pin to the load.
  3. For the adjustable version, use external resistors to set the desired output voltage.
  4. Ensure proper heat sinking to maintain thermal performance.

Caution:

  • Do not exceed the maximum input voltage to avoid damaging the regulator.
  • Provide adequate heat sinking to prevent thermal shutdown.
  • Avoid short circuits to protect the regulator and load.
