LM337KCSE3集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LM337KCSE3属于集成电路（IC）的线性+开关稳压器。由美国德州仪器公司制造生产的LM337KCSE3稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。

3 Description

The LM237 and LM337 are adjustable 3-terminal

negative-voltage regulators capable of supplying in

excess of –1.5 A over an output voltage range of –1.2

V to –37 V. They require only two external resistors

to set the output voltage and one output capacitor for

frequency compensation.
