SI-3090KM

1 A, Low-Dropout, 9.0 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-3090KM 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.

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.
