MIC49500  
5A Dual Supply, Low Voltage,  
High Bandwidth LDO  
General Description  
Features  
The MIC49500 is an ultra-high-bandwidth, low-  
dropout, 5.0A voltage regulator ideal for powering  
core voltages of low-voltage microprocessors. The  
MIC49500 implements a dual supply configuration  
allowing for very low output impedance and very fast  
transient response.  
• Input voltage range:  
–
–
VIN: 1.4V to 6V  
VBIAS: 3.0V to 6V  
• Stable with 10µF ceramic output capacitor  
• +1.0% initial output tolerance  
• Maximum dropout (VIN – VOUT) is 500mV over  
temperature  
The MIC49500 requires a bias input supply and a  
main input supply, allowing for ultra-low input voltages  
on the main supply rail. The input supply operates  
from 1.4V to 6V and the bias supply requires between  
3V and 6V for proper operation. The MIC49500 can  
regulate to an output voltage as low as 0.7V, making it  
an ideal product for low-voltage to low-voltage  
conversion.  
• Adjustable output voltage down to 0.7V  
• Ultra Fast Transient Response (Up to 10MHz  
bandwidth)  
• Excellent line and load regulation specifications  
• Logic controlled shutdown option  
• Thermal shutdown and current limit protection  
• Thin 7-pin S-Pak package  
• TO-263 7-pin package  
• –40°C to +125°C operating junction temperature  
range  
The MIC49500 requires  
a minimum of output  
capacitance for stability, working optimally with any  
type of capacitor, including small ceramic capacitors.  
Available in fixed output voltages from 0.9V to 1.8V  
and adjustable output voltages down to 0.7V, the  
MIC49500 comes in both 7-pin S-Pak and TO-263  
packages. The MIC49500 is rated to the full operating  
temperature range of –40°C to 125°C junction  
temperature.  
Applications  
• ASIC Core Voltage Regulator  
• PLD/FPGA Core Power Supply  
• Linear Point-of-Load Conversion  
• High Speed Post-Regulator
