Product Overview

The LM337T is an adjustable 3-terminal Negative Voltage Regulator, capable of supplying in excess of -1.5A over an output voltage range of -1.2V to -37V. This regulator is exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 series features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads. The LM337T serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM337T is ideal complements to the LM117/LM317 adjustable positive regulators.
  • Output voltage adjustable from -1.2 to -37V
  • 1.5A Output current specified, -55 to +150°C
  • Line regulation typically 0.01%/V
  • Load regulation typically 0.3%
  • 0.002%/W Excellent thermal regulation
  • 77dB Ripple rejection
  • Excellent rejection of thermal transients
  • 50ppm/°C Temperature coefficient
  • Temperature-independent current limit
  • Internal thermal overload protection
  • P+ Product enhancement tested
  • Short-circuit protection for output
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.
