AS1583
1.5A Ultra Low Dropout Voltage Regulator
Fast Response, Adjustable & Fixed
FEATURES
Low Dropout Voltage 500mV at 1.5A Full Load Current
Adjustable Output Down to 1.2V from ATX Power Supply
Fixed Output Voltages of 3.3V, 2.8V, 2.5V, and 1.5V
Extremely Tight Voltage and Line Regulation
Standard 5-Terminal Low Cost TO-220 & TO-263
PRODUCT DESCRIPTION
The AS1583 is a 1.5A 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 AS1583 features a low dropout of less than 400mV(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 AS1583 is also an excellent choice as a post regulator for switching supplies applications.
The AS1583 offers full protection against over-current faults, reversed input polarity, over temperature operation and positive and
negative transient voltage.
The AS1583 is offered in a 5 pin TO-220 and TO-263 compatible with industry standard 5-terminal regulators. For 7A, 5A and 3A
ultra low dropout versions refer to AS1580, AS1581 and AS1582 data sheets respectively.
