簡單介紹
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 transie
詳情介紹
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, programmable-output voltage regulation or precision current regulation. The LM137 are ideal complements to the LM117 adjustable positive regulators.
