DESCRIPTION

The LX8580 is a high-performance, very low dropout voltage regulator, designed for use with advanced microprocessors. This product can be used with separate voltage supplies for the control and power sections, allowing a power section dropout voltage as low as 100mV. The LX8580 can also be used in a single voltage supply configuration, with a dropout performance similar to that of the LX8584 (1.3V at 7A).

KEY FEATURES

■ Low Dropout, 800mV Max. at 7A Output Current in Dual Supply Mode

■ Fast Transient Response

■ Remote Sensing

□ 1mV Load Regulation

□ Adjustable Output

□ No Supply Sequencing Problems in Dual Supply Mode

APPLICATIONS

■ Microprocessor Supplies

■ 3.3V to 2.5V Processor Power Supplies

■ High-Current Regulators

■ Post Regulators for Switching Supplies

LX8580-00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LX8580-00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。
