DESCRIPTION  
FEATURES  
The EZ1588 series of high performance positive  
voltage regulators are designed for use in applications  
requiring low dropout performance at full rated current.  
Additionally, the EZ1588 series provides excellent  
regulation over variations in line, load and temperature.  
= Low dropout performance,  
1.3V max. for EZ1588  
= Full current rating over line and temperature  
= Fast transient response  
= ±2% total output regulation over 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 EZ1588 series are three terminal  
regulators with fixed and adjustable voltage options  
available in popular packages.  
= Adjust pin current max. 90µA over temperature  
= Fixed/adjustable output voltage  
= Line regulation typically 0.005%  
= Load regulation typically 0.05%  
= TO-220 or TO-263 packages
