LML337HVH
LML337HVH is 3-Terminal Adjustable Negative Regulators manufactured by National Semiconductor.
Description The LM137HV/LM337HV are adjustable 3-terminal negative voltage regulators capable of supplying in excess of - 1.5A over an output voltage range of - 1.2V to - 47V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency pensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137HV series features internal current limiting, thermal shutdown and safe-area pensation, making them virtually blowout-proof against overloads. The LM137HV/LM337HV serve a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137HV/LM337HV are ideal plements to the LM117HV/LM317HV adjustable positive regulators.
