Product Overview

The LM2596S-5.0/NOPB is a step-down Voltage Regulator, provides all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. This device is available in fixed output voltages of 3.3, 5, 12V 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 LM2596S-5.0/NOPB series operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
  • Ensured 3A Output Load Current
  • Input Voltage Range up to 40V
  • Requires Only 4 External Components
  • Excellent Line and Load Regulation Specifications
  • 150kHz Fixed Frequency Internal Oscillator
  • TTL Shutdown Capability
  • Low-power Standby Mode, IQ Typically 80μA
  • High Efficiency
  • Uses Readily Available Standard Inductors
  • Thermal Shutdown and Current Limit Protection
