High Performance 2A and 3A Linear Regulators  
ISL80102, ISL80103  
Features  
• Stable with all Capacitor Types (Note 11)  
• 2A and 3A Output Current Ratings  
• 2.2V to 6V Input Voltage Range  
The ISL80102 and ISL80103 are low voltage,  
high-current, single output LDOs specified for 2A and 3A  
output current, respectively. These LDOs operate from  
input voltages of 2.2V to 6V and are capable of providing  
output voltages of 0.8V to 5V on the adjustable V  
• ±1.8% V  
Accuracy Guaranteed Over Line, Load

versions. Fixed output voltage options are available in  
1.5V, 1.8V, 2.5V, 3.3V and 5V. Other custom voltage  
options available upon request.  
and T = -40°C to +125°C

• Very Low 120mV Dropout Voltage at 3A (ISL80103)  
• Fixed and Adjustable V

Versions  
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 sub-micron BiCMOS process is utilized for this  
product family to deliver the best in class analog  
performance and overall value.  
• Very Fast Transient Response  
• Excellent 62dB PSRR  
• 100µV  
RMS  
Output Noise  
• Power-Good Output  
• Adjustable In-Rush Current Limiting  
• Short Circuit and Over-Temperature Protection  
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. Quiescent  
current is 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.  
• Available in a 10 Ld DFN (now), 5Ld TO220 and 5Ld  
TO263 (soon)
