DESCRIPTION

The

SPX1580 is a 7A Low Dropout Regulator with extremely low dropout voltage. The adjustable version

requires only two external resistors to set the output voltage. The fixed version has a preset output of 3.3V

or 2.5V and does not require any external resistors. The SPX1580 features a low dropout of 540mV(Typ.)

and offers fast transient response. This device is suitable for Pentium applications requiring 2.5V from 3.3V

ATX power supplies, where a low current input voltage 1V greater than the output voltage is available. 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. The SPX1580 is also an excellent choice as a post regulator for switching

supplies applications.

The SPX1580 offers protection against over-current faults, reversed input polarity, over temperature

operation and positive and negative transient voltage.

The SPX1580 is offered in a 5 pin TO-220 and TO-263 compatible with industry standard 5-terminal

regualtors. For 5A, 3A and 1.5A ultra low dropout versions refer to SPX1581, SPX1582 and SPX1583 data

sheets respectively.
