MIC49150  
1.5A Low Voltage LDO Regulator  
w/Dual Input Voltages  
General Description  
Features  
The MIC49150 is a high-bandwidth, low-dropout, 1.5A volt-  
age regulator ideal for powering core voltages of low-  
power microprocessors. The MIC49150 implements a dual  
supply conguration allowing for very low output  
impedance and very fast transient response.  
Input Voltage Range:  
VIN: 1.4V to 6.5V  
BIAS: 3.0V to 6.5V  
V
Stable with 1µF ceramic capacitor  
±1% initial tolerance  
The MIC49150 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  
6.5V and the bias supply requires between 3V and 6.5V  
for proper operation. The MIC49150 offers xed output  
voltages from 0.9V to 1.8V and adjustable output voltages  
down to 0.9V.  
Maximum dropout voltage (VIN–VOUT) of 500mV  
over temperature  
Adjustable output voltage down to 0.9V  
Ultra fast transient response (Up to 10MHz bandwidth)  
Excellent line and load regulation specications  
Logic controlled shutdown option  
Thermal shutdown and current limit protection  
Power MSOP-8 and S-Pak packages  
The MIC49150 requires a minimum of output capacitance  
for stability, working optimally with small ceramic  
capacitors.  
Junction temperature range: –40°C to 125°C  
The MIC49150 is available in an 8-pin power MSOP pack-  
age and a 5-pin S-Pak. Its operating temperature range is  
–40°C to +125°C.
