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.
