ADD MICROTECH CORP.
7A LOW DROPOUT REGULATOR

DESCRIPTION FEATURES
The AMC7580 is a high performance low dropout regulator
rated for 7A output current with fixed 2.5V/3.3V/5.0V and
adjustable output. It is designed for use in applications requiring
low dropout characteristics over the rated current range.
When the second low-current input voltage is applied, the drop
out voltage can be as low as 100mV at light loads and up to
500mV at maximum output current. On chip trimming adjusts
the reference voltage to 1%. These features are ideal for low
voltage microprocessor applications requiring a regulated 2.5V
to 3.6V power supply.
In addition, the AMC7580 provides the device protections
including over current and thermal shutdown. The AMC7580
series are ideal to the next generation microprocessor on
motherboards where both 5V and 3.3V are available.
