SC1563  
Very Low Dropout, Low  
Quiescent 500mA Regulator  
POWER MANAGEMENT  
Description  
ꢀeatures  
The SC1563 is a high performance positive voltage  
regulator designed for use in applications requiring very  
low dropout voltage at up to 500mA. Since it has supe-  
rior dropout characteristics compared to regular LDOs, it  
can be used to supply 2.5V on motherboards or 2.8V on  
peripheral cards from the 3.3V supply with no heatsink.  
Additionally, the SC1563 has a shutdown pin to further  
reduce power dissipation while shut down. The SC1563  
provides excellent regulation over variations in line, load  
and temperature.  
u 350mV dropout @ 500mA  
u Designed to operate with ceramic capacitors  
u Adjustable output from 1.2V to 4.8V  
u Multiple output voltage options (all parts also  
adjustable externally using resistors)  
u Over current and over temperature protection  
u 2µA quiescent current in shutdown  
u No minimum load current requirement  
u Low reverse leakage (output to input)  
u ꢀull industrial temperature range  
u SOT-23-5 and MSOP-8 surface mount packages  
A wide range of fixed output voltage options are  
available. In addition, the output voltage of every device  
can be adjusted between 1.2V and 4.8V using external  
resistors. The SC1563 comes in both 5-pin  
SOT-23 and 8-pin MSOP packages to allow the user to  
select a package suitable for their spacing and heat  
dissipation needs.  
Applications  
u Personal Digital Assistants  
u Battery powered systems  
u Motherboards  
u Peripheral cards  
u PCMCIA cards
