PRODUCT DESCRIPTION

The AS1580 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, 2.8V or 2.5V and does not require any external

resistors. The AS1580 features a low dropout of 540mV(Typ.) and offers fast transient response. This device is suitable for Pentium

applications requiring 2.8V or 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 in

powering low voltage microprocessors that require a lower dropout, fast transient response to regulate from 3.3V and 5V supplies.

The AS1580 is also an excellent choice as a post regulator for switching supplies applications.

The AS1580 offers protection against over-current faults, reversed input polarity, over temperature operation and positive and negative

transient voltage.

The AS1580 is offered in a 5 pin TO-220 and TO-263 compatible with industry standard 5-terminal regulators. For 5A, 3A and 1.5A

ultra low dropout versions refer to AS1581, AS1582 and AS1583 data sheets respectively
