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-3010LLSL voltage regulator

offers the reduced dropout voltage and low quiescent current essential

for improved efficiency. This device delivers a regulated output at up to

1.5 A. Integrated thermal and overcurrent protection enhance overall

system reliability.

An npn pass element provides a dropout voltage of less than 300

mV at 1 A of load current. Regulator accuracy and excellent tempera-

ture characteristics are provided by a bandgap reference. Low output

voltages eliminate the need for expensive PWM buck converters. The

low dropout voltage permits more efficient regulation before output

regulation is lost. 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. An LS-TTL/CMOS-

compatible input gives the designer complete control over power up,

standby, or power down.

This devices is supplied in a fully molded 8-lead miniature surface-

mount package (tape and reel) with enhanced power-dissipating qualities.

It is rated for continuous operation between -30°C and +100°C.
