1 A, Low-Dropout, 12 V RegulatorDesigned to meet the high-current requirements in industrial and
consumer applications; embedded core, memory, or Logic supplies; TVs
VCRs, and office equipment, the SI-3120KM 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 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 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. By Allegro MicroSystems, Inc. |
