Dual Input Low Dropout Regulator  
POWER MANAGEMENT  
Description  
Features  
The EZ158X family of high performance positive voltage  
regulators are designed for use in applications requiring  
very low dropout voltage at up to 7, 5, 3 and 1.5 amps.  
Capable of supplying up to 2.8V on boards where both  
5V and 3.3V supplies are available, the superior dropout  
characteristics of the EZ158X result in reduced heat  
dissipation compared to regular LDOs. This allows for  
heatsink size reduction or elimination. Additionally, the  
EZ158X provides excellent regulation over variations in  
line, load and temperature. Remote sense operation  
allows compensating for trace, connector and other  
resistive losses.  
u 540mV dropout @ 7A in dual supply mode  
(EZ1580)  
u Remote sense operation  
u Fast transient response  
u 0.5% initial accuracy  
u Line regulation typically 0.08%  
u Load regulation typically 0.08%  
u 5 Pin TO-220 and TO-263 packages  
Applications  
u Microprocessor supplies  
u Split plane microprocessor supplies  
u Advanced graphics cards  
u Sound cards  
u Low voltage logic supplies  
u Switching power supply post regulation  
Outstanding features include very low dropout  
performance at rated current, fast transient response,  
remote sense, internal current limiting, thermal shutdown  
and safe operating area protection of the output device.  
The EZ158X is a five terminal adjustable voltage regula-  
tor available in the popular 5 pin TO-220 and TO-263  
plastic packages.

Notes:  
(1) Capacitor values are for reference only. Good quality, low ESR tantalum or aluminum electrolytic capacitors  
should be used. Increasing the value of the output capacitor will improve the overall transient response.  
(2) If the same voltage is input to both PWR and CTL, then the dropout voltage will become 1.3V maximum.  
(3) A small (~0.033µF) capacitor can be used to bypass the ADJ pin to improve transient response, if needed.
