LM137HVQML www.ti.com SNVS314A – DECEMBER 2010 – REVISED APRIL 2013 LM137HVQML 3-Terminal Adjustable Negative Regulators (High Voltage) Check for Samples: LM137HVQML FEATURES 1 2 Output Voltage Adjustable from −47V to −1.2V 1.5A Output Current Specified, −55°C ≤ TJ ≤ +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 Short Circuit Protected DESCRIPTION The LM137HV is an adjustable 3-terminal negative voltage regulator capable of supplying in excess of −1.5A over an output voltage range of −47V to −1.2V. This regulators 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 LM137HV features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads. The LM137HV serves a wide variety of applications including local on-card regulation, programmableoutput voltage regulation or precision current regulation. The LM137HV is an ideal complement to the LM117HV adjustable positive regulator. Connection Diagrams See Physical Dimens...
