Product Overview

The LM2594M-5.0/NOPB is a simple monolithic Switcher® low component count Step-down Voltage Regulator provides all the active functions for a step-down (buck) switching regulator, capable of driving a 0.5A load with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use and feature internal frequency compensation, a fixed-frequency oscillator and improved line and load regulation specifications. The LM2594M-5.0/NOPB operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed.
  • Requires only 4 external components
  • 150kHz Fixed frequency internal oscillator
  • TTL shutdown capability
  • Low power standby mode, IQ typically 85μA
  • High efficiency
  • Uses readily available standard inductors
  • Thermal shutdown and current limit protection


Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
