Overview

The LM337 is an adjustable 3-terminal negative linear voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of -1.2V to -37 V. This linear voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow-out proof.

The LM337 serves a wide variety of applications including local, on card regulation. This linear voltage regulator can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM337 can be used as a precision current regulator.

  • Output Current in Excess of 1.5 A
  • Output Adjustable between -1.2 V and -37 V
  • Internal Thermal Overload Protection
  • Internal Short Circuit Current Limiting Constant with Temperature
  • Output Transistor Safe-Area Compensation
  • Floating Operation for High Voltage Applications
  • Eliminates Stocking many Fixed Voltages
  • Available in Surface Mount D2PAK and Standard 3-Lead Transistor Package
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
