DESCRIPTION
The SPX1582 features a low dropout of 400mV(Typ.) and offers fast transient response. This device is suitable for Pentium applications requiring 2.8V, 2.5V from 3.3V ATX power supplies, where a low current input voltage 1V greater than the output voltage is needed. With an external sense pin the load regulation is less than 1mV. This device is an excellent choice for the use of powering low voltage microprocessors that require a lower dropout, fast transient response to regulate from 3.3V and 5V supplies.
