SC1566  
Very Low Dropout  
3.0 Amp Regulator With Enable  
POWER MANAGEMENT  
Description  
Features  
The SC1566 is a high performance positive voltage  
regulator designed for use in applications requiring very  
low dropout voltage at up to 3 Amps. Since it has  
superior 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 thus  
allowing heat sink size reduction or elimination.  
Additionally, the five pin versions of SC1566 have an  
enable pin, to further reduce power dissipation while shut  
down. The SC1566 provides excellent regulation over  
variations in line, load and temperature.  
‹ 350mV dropout @ 3A  
‹ Adjustable output from 1.2V to 4.8V  
‹ 2.5V and 1.8V options (5 pin parts also adjustable  
externally using resistors)  
‹ Over current and over temperature protection  
‹ Enable pin  
‹ 10µA quiescent current in shutdown  
‹ Low reverse leakage (output to input)  
‹ Full industrial temperature range  
‹ TO-220 and TO-263 packages  
Applications  
The SC1566 is available as three terminal fixed output  
voltage and five terminal fixed or adjustable output  
voltage devices with enable. Two package options are  
available: TO-263 and TO-220.  
‹ Battery powered systems  
‹ Motherboards and notebook computers  
‹ Peripheral cards  
‹ Network cards  
‹ Set top boxes  
‹ Medical equipment
