DATASHEET  
High Performance 2A and 3A Linear Regulators  
ISL80102, ISL80103  
The ISL80102 and ISL80103 are low voltage, high-current, single  
output LDOs specified for 2A and 3A output current, respectively.  
These LDOs operate from the input voltages of 2.2V to 6V and  
are capable of providing the output voltages of 0.8V to 5.5V on  
Features  
• Stable with ceramic capacitors (Note 11)

• Very low 120mV dropout voltage at 3A (ISL80103)  
For applications that demand in-rush current less than the  
current limit, an external capacitor on the soft-start pin provides  
adjustment. The ENABLE feature allows the part to be placed into  
a low quiescent current shutdown mode. A submicron BiCMOS  
process is utilized for this product family to deliver the  
best-in-class analog performance and overall value.

• Power-good output  
These CMOS (LDOs) will consume significantly lower quiescent  
current as a function of load over bipolar LDOs, which translates  
into higher efficiency and the ability to consider packages with  
smaller footprints. The quiescent current has been modestly  
compromised to enable a leading class fast load transient  
response, and hence a lower total AC regulation band for an LDO  
in this category.
