LM137JAN www.ti.com SNVS332B – DECEMBER 2010 – REVISED MARCH 2013 LM137JAN 3-Terminal Adjustable Negative Regulators Check for Samples: LM137JAN FEATURES 1 2 Output Voltage Adjustable from −37V to −1.2V 1.5A Output Current Specified, −55°C to +150°C Line Regulation Typically 0.01%/V Load Regulation Typically 0.3% Excellent Thermal Regulation, 0.002%/W 77 dB Ripple Rejection Excellent Rejection of Thermal Transients 50 ppm/°C Temperature Coefficient Temperature-independent Current Limit Internal Thermal Overload Protection Standard 3-lead Transistor Package Output is Short Circuit Protected DESCRIPTION The LM137 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of −1.5A over an output voltage range of −37V to −1.2V. These regulators are 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 LM137 serves a wide variety of applications including local on-card regulation, programmableoutput voltage regulation or precision current regulation. The LM137 are ideal complements to the LM117 adjustable positive regulators. Connection Diagram Case is Input Figure 1. TO-3 Metal Can Packag...
