DESCRIPTION  
FEATURES  
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.  
Low dropout performance,  
1.3V max. for EZ1585  
Full current rating over line and temperature  
Fast transient response  
±2% total output regulation over line, load  
and temperature  
Adjust pin current max 90µA over temperature  
Fixed/adjustable output voltage  
Line regulation typically 0.015%  
Load regulation typically 0.05%  
TO-220 or TO-263 packages  
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.
