由凌力尔特公司提供采用 H（金属圆帽）、J（陶瓷）和 K（金属圆帽）封装的器件现已停产.。 LT®137A/LT337A 负电压可调稳压器将在 -1.2V 至 -37V 的输出电压范围内提供高达 1.5A 的输出电流。与早先推出的器件相比，凌力尔特对这些稳压器进行了显著的改进，例如：更加优越的电压和负载调节性能，以及一个 1% 的最大输出电压误差。 凌力尔特竭尽全力地使这些器件拥有易用性和抗损性。内部电流和功率限制、再加上真正的热限制功能，可避免器件遭受因过载或短路所造成的损坏，即使在稳压器未被固定于散热器上的情况下也不例外。 凭借凌力尔特先进的加工工艺以及热限制模式中的全面高温老化，实现了最高的可靠性。这将确保所有的器件保护电路都正常运行，并消除了其他那些仅接受了标准电气测试的稳压器时有发生的现场故障。 \n

The LM137 and LM337-N are adjustable 3-terminal negative voltage regulators capable of supplying–1.5 A or more currents over an output voltage range of –1.25 V to –37 V. It requires only two external resistors to set the output voltage and one output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 and LM337-N feature internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads.\n\n The LM137 and LM337-N are ideal complements to the LM117 and LM317 adjustable positive regulators. The LM137 has a wider operating temperature range than the LM337-N and is also offered in military and space qualified versions.
