DATASHEET  
High Performance 1A LDO  
ISL80101  
Features  
The ISL80101 is a low voltage, high current, single output LDO  
specified at 1A output current. This LDO operates from input  
voltages of 2.2V to 6V. Fixed output voltage options are  
available in 1.8V, 2.5V, 3.3V and 5.0V versions. Other custom  
voltage options are available upon request. For the adjustable  
output version of the ISL80101, please refer to the  
ISL80101-ADJ datasheet.  
• ±1.8% V  
accuracy guaranteed over line, load and  
T = -40°C to +125°C

• Very low 130mV dropout voltage at V  
• Very fast transient response  
• Programmable soft-starting  
• Power-good output

OUT  
A submicron BiCMOS process is utilized for this product family  
to deliver the best-in-class analog performance and overall  
value. This CMOS LDO consumes significantly lower quiescent  
current as a function of load compared to bipolar LDOs, which  
translates into higher efficiency and packages with smaller  
footprints. State-of-the-art internal compensation achieves a  
very fast load transient response. An external capacitor on the  
soft-start pin provides an adjustable soft-starting ramp. The  
ENABLE feature allows the part to be placed into a low  
quiescent current shutdown mode. A power-good logic output  
signals a fault condition.  
• Excellent 65dB PSRR  
• Current limit protection  
• Thermal shutdown function  
• Available in a 10 Ld DFN package  
• Pb-free (RoHS compliant)  
Applications  
• DSP, FPGA and µP core power supplies  
• Noise-sensitive instrumentation systems
