Description

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-3011ZF

voltage regulator offers the reduced dropout voltage and low

quiescent current essential for improved 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.

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 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.

This device is supplied in a fully molded TO-220-style 5-lead

flange-mounted, high power, isolated plastic package. Asimilar

device in a lower-power surface-mount plastic package is the

SI-3011ZD.
