MIC49150  
1.5A Low Voltage LDO Regulator w/Dual Input Voltages  
Final Information  
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  
configuration allowing for very low output impedance and  
very fast transient response.  
Input Voltage Range:  
V : 1.4V to 6.5V  
IN  
V
: 3.0V to 6.5V  
BIAS  
Stable with 1µF ceramic capacitor  
±1% initial tolerance  
Maximum dropout voltage (V -V  
) of 500mV over  
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 fixed output voltages from  
0.9V to 1.8V and adjustable output voltages down to 0.9V.  
IN OUT  
temperature  
Adjustable output voltage down to 0.9V  
Ultra fast transient response (Up to 10MHz bandwidth)  
Excellent line and load regulation specifications  
Logic controlled shutdown option  
Thermal shutdown and current limit protection  
Power MSO-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 package  
and a 5-pin S-Pak. Its operating temperature range is –40°C  
to +125°C.  
Applications  
Graphics processors  
PC Add-In Cards  
Microprocessor core voltage supply  
Low voltage digital ICs  
High Efficiency Linear power supplies  
SMPS post regulators
