DESCRIPTION

The LX8580A is a highperformance, very low dropout voltage regulator, designed for use with advanced microprocessors, microcontrollers, or video graphics controllers. This product can be used with separate voltage supplies for the control and power sections, allowing a power regulation dropout voltage as low as 100mV @ 1.5A. In AGP bus systems requiring regulation of 3.3V to 2.85V @ 3A, the LX8580A has a max dropout of 250mV making it an ideal power supply solution for today’s graphics applications.

LX8580A-00CDF属于集成电路（IC） > 线性 + 开关稳压器。美高森美公司制造生产的LX8580A-00CDF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。
