EZ1584C & EZ1584I  
7.0 Amp Low Dropout  
Positive Voltage Regulators  
POWER MANAGEMENT  
Description  
ꢀeatures  
The EZ1584 is a high performance positive voltage  
regulator designed for use in applications requiring low  
dropout performance at 7A. Additionally, the EZ1584  
series provides excellent regulation over variations in line,  
load and temperature.  
u Low dropout performance: 1.3V max. for EZ1584C  
and 1.4V max. for EZ1584I  
u ꢀull current rating over line and temperature  
u ꢀast transient response  
u ±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.  
u Adjust pin current max 90µA over temperature  
u ꢀixed/adjustable output voltage  
u Line regulation typically 0.015%  
u Load regulation typically 0.05%  
u Industrial temperature range (EZ1584I)  
u TO-220 package  
The EZ1584 is an excellent choice for powering  
microprocessor systems. Using an LDO eliminates  
MOSꢀETs and inductors, saving both space and cost. An  
LDO also provides better transient response and no  
ripple.  
Applications  
u Memory supply  
u Graphics core supply  
A variety of options are available for maximum flexibility:  
the EZ1584C is intended for commercial applications and  
has both fixed and adjustable voltage options; the  
EZ1584I is intended for industrial applications and has  
a 3.3V fixed and an adjustable option. All devices are  
available in the popular TO-220 package.  
u Other 2.5V to 3.6V microprocessor supplies  
u Low voltage logic supplies  
u Battery-powered circuitry  
u Post regulator for switching supply  
u Telecom supplies  
u Industrial supplies
