SI-3005KWM  
1 A, Low-Dropout, Dual Output, 1.5 V & 1.8 V Regulator  
Designed to meet the high-current requirements in industrial and  
consumer applications; embedded core, memory, or logic supplies; TVs,  
VCRs, and office equipment, the SI-3005KWM voltage regulator offers  
the reduced dropout voltage and low quiescent current essential for  
improved efficiency. This device delivers dual regulated outputs at up to  
1 A. Integrated thermal and overcurrent protection enhance overall  
system reliability. Devices with other output voltages are also available.  
Quiescent current does not increase significantly as the dropout  
voltage is approached, an ideal feature in standby/resume power systems  
where data integrity is crucial. Regulator accuracy and excellent  
temperature characteristics are provided by a bandgap reference. An  
LS-TTL/CMOS-compatible input gives the designer complete control  
over Channel 1 (1.8 V) power up, standby, or power down. A pnp pass  
element provides a dropout voltage of less than 600 mV at 1 A of load  
current. Low output voltages eliminate the need for expensive PWM  
buck converters. The low dropout voltage permits more efficient  
regulation before output regulation is lost.  
This device is supplied in a 5-lead TO-252 style surface-mount  
plastic package with ground tab to provide a low-resistance path for  
maximum heat dissipation.
