SI-3033LSA

LOW-VOLTAGE, HIGH-CURRENT

3.3 V LINEAR REGULATOR

The SI-3033LSA is designed to meet the requirement for increased

integration and reliability in low-voltage, high-current, linear regulator

applications such as personnel computers (PCs) and set-top boxes.

Each device incorporates a monolithic low-level reference and control

circuit with a high-current pnp transistor in a power multi-chip module

(PMCM™). Regulated output voltages of 1.8 V or 2.5 V are also

available.

INTERNAL

CONNECTION

SUB

SUPPLY

ENABLE

The high-current pass element provides a low dropout voltage with

output current to 1 A. Regulator accuracy of ±2 % and excellent

temperature characteristics are provided. The logic-compatible

ENABLE input gives the designer complete control over power up,

power down, and standby or sleep.

Dwg. PK-012

These devices are supplied in a fully molded 8-lead miniature

surface-mount package (tape and reel) with enhanced power-dissipating

qualities. They are rated for continuous operation between -30°C and

+100°C.

* Output current rating may be limited by duty

cycle, ambient temperature, and heat sinking.

Under any set of conditions, do not exceed the

specified current rating or a junction temperature

of 150˚C.

† Fault conditions that produce excessive

junction temperature will activate the device’s

thermal shutdown circuitry. These conditions

can be tolerated but should be avoided.

Always order by complete part number: SI-3033LSA-TL ,

where “-TL” indicates tape and reel.
