MIC47150  
1.5A, Low Voltage, Adjustable, High-  
Bandwidth LDO Regulator with Dual Input  
Supplies  
General Description  
Features  
The MIC47150 is a high-bandwidth, low-dropout, 1.5A volt-  
age regulator ideal for powering core voltages of low-  
power microprocessors. The MIC47150 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 MIC47150 requires a bias input supply between 3V  
and 6.5V for proper operation. The main input supply rail  
operates from 1.4V to 6.5V that allows for 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 specifications  
Power D-Pak package (TO-252)  
Thermal shutdown and current-limit protection  
Junction temperature range: –40°C to +125°C  
The MIC47150 requires a minimum of 1µF output  
capacitance for stability, and optimal operation is achieved  
with small ceramic capacitors.  
The MIC47150 is available in a 5-pin power D-Pak  
package (TO-252) with an operating temperature range of  
–40°C to +125°C.  
Datasheets and support documentation can be found on  
Micrel’s web site at www.micrel.com.  
Applications  
Graphics processors  
PC add-in cards  
Microprocessor core voltage supply  
Low voltage digital ICs  
High efficiency linear power supplies  
SMPS post regulators
