DESCRIPTION
The EZ1585D is a high performance positive voltage regulator designed for use in applications requiring low dropout performance at full rated current. Additionally, the EZ1585D 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 EZ1585D has tight tolerance on reference voltage, 1% at 25C and 1.5% over line, load and temperature, as well as a 6.0A maximum current. The EZ1585D is a three terminal regulator with adjustable output voltage available in the popular TO220 package.
FEATURES *= Low dropout performance, 1.3V max. *= Full current rating over line and temperature *= Fast transient response *= 1.5% total output regulation over line, load *= *= *= *= *=
and temperature Adjust pin current max. 100A over temperature Adjustable output voltage Line regulation typically 0.015% Load regulation typically 0.05% TO-220 package
APPLICATIONS *= Pentium(R) Processor supplies ORDERING INFORMATION
