consumer applications; embedded core, memory, or logic supplies; TVs,
VCRs, and office equipment, the SI-3011ZF voltage regulator offers the
reduced dropout voltage and low quiescent current essential for im-
proved efficiency. This device delivers a regulated output at up to 3 A.
Integrated thermal and overcurrent protection enhance overall system
reliability. Devices with fixed output voltages of 2.5 V or 3.3 V are also
available.
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 700 mV at 3 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.
flange-mounted , high power, isolated plastic package. A similar device
in a lower-power surface-mount plastic package is the SI-3011ZD.
