The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed frequency oscillator.

The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. Available in a standard 5-pin TO-220 package with several different lead bend options, and a 5-pin TO-263 surface mount package.

  • 3.3-V, 5-V, 12-V, and adjustable output versions 
  • Adjustable version output voltage range: 1.2-V to 37-V ±4% maximum over line and load conditions 
  • Available in TO-220 and TO-263 packages 
  • 3-A output load current • Input voltage range up to 40 V 
  • Requires only four external components 
  • Excellent line and load regulation specifications 
  • 150-kHz Fixed-frequency internal oscillator 
  • TTL shutdown capability 
  • Low power standby mode, IQ, typically 80 μA 
  • High efficiency 
  • Uses readily available standard inductors 
  • Thermal shutdown and current-limit protection 
  • Create a custom design using the LM2596 with the WEBENCH Power Designer
