* Output current rating is limited by input
voltage, duty cycle, and ambient tempera-
ture. Under any set of conditions, do not
exceed a junction temperature of +125°C.
Designed to meet the high-current requirements in industrial and
consumer applications; embedded core, memory, or logic supplies;
TVs, VCRs, and ofce equipment, the SI-3010LLSL voltage regulator
offers the reduced dropout voltage and low quiescent current essential
for improved efciency. 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 efcient regulation before output
regulation is lost. Quiescent current does not increase signicantly 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 deviceswww.DataSheet4U.com 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.
