SI-3018LSA  
LOW-VOLTAGE, HIGH-CURRENT  
1.8 V LINEAR REGULATOR  
The SI-3018LSA is designed to meet the requirement for increased  
integration and reliability in low-voltage, high-current, linear regulator  
applications such as personal 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 2.5 V or 3.3 V are also  
available.

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 protection circuitry. These conditions  
can be tolerated but should be avoided.  
Always order by complete part number: SI-3018LSA-TL ,  
where “-TL” indicates tape and reel.
