DESCRIPTION
The EZ1585 series of high performance positive
voltage regulators are designed for use in applications
requiring low dropout performance at full rated
current. Additionally, the EZ1585 series provides
excellent regulation over variations in line, load and
temperature.
Outstanding features include low dropout
performance at rated current, fast transient response,
internal current limiting and thermal shutdown
protection of the output device. The EZ1585 series
are three terminal regulators with fixed and adjustable
voltage options available in popular packages.
APPLICATIONS
• Pentium^® Processor supplies
• PowerPC™ supplies
• Other 2.5V to 3.6V microprocessor supplies
• Low voltage logic supplies
• Battery-powered circuitry
• Post regulator for switching supply
