LX8586A-33CP集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LX8586A-33CP属于集成电路（IC）的线性+开关稳压器。由美高森美公司制造生产的LX8586A-33CP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。

DESCRIPTION

The LX8586/86A series ICs are low dropout three-terminal regulators with a minimum of 6A output current. Pentium® Processor, Power PCTM, Cyrix® 6x86TM and AMD-K5TM applica tions requiring fast transient response are ideally suited for this product family. The LX8586A is guaranteed to have < 1.1V at 6A and the LX8586 < 1.3V at 6A dropout voltage, making them ideal to provide well-regulated outputs of 2.5V to 3.6V using a 5V input supply. Fixed versions are also available and specified in the Available Options table below.
