LM317L集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LM317L属于集成电路（IC）的线性+开关稳压器。由安森美半导体制造生产的LM317L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。

The LM317L is an adjustable 3−terminal positive voltage regulator

capable of supplying in excess of 100 mA over an output voltage range

of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use

and requires only two external resistors to set the output voltage.

Further, it employs internal current limiting, thermal shutdown and

safe area compensation, making them essentially blow−out proof.

The LM317L serves a wide variety of applications including local,

on card regulation. This device can also be used to make a

programmable output regulator, or by connecting a fixed resistor

between the adjustment and output, the LM317L can be used as a

precision current regulator.
