FEATURES  
DESCRIPTION  
2
•
Ultra-Low VIN and VOUT Range: 0.8V to 5.5V  
The TPS74701 low-dropout (LDO) linear regulator  
provides an easy-to-use, robust power management  
•
•
•
VBIAS Range 2.7V to 5.5V  
Low Dropout: 50mV typ at 500mA, VBIAS = 5V  
solution for  
a
wide variety of applications.  
Power Good (PG) Output Allows Supply  
Monitoring or Provides a Sequencing Signal  
for Other Supplies  
User-programmable soft-start minimizes stress on the  
input power source by reducing capacitive inrush  
current on start-up. The soft-start is monotonic and  
well-suited for powering many different types of  
processors and ASICs. The enable input and power  
good output allow easy sequencing with external  
regulators. This complete flexibility permits the user to  
configure a solution that meets the sequencing  
requirements of FPGAs, DSPs, and other  
applications with special start-up requirements.  
•
•
2% Accuracy Over Line/Load/Temperature  
Programmable Soft-Start Provides Linear  
Voltage Startup  
•
VBIAS Permits Low VIN Operation with Good  
Transient Response  
•
•
Stable with Any Output Capacitor ≥ 2.2µF  
A precision reference and error amplifier deliver 2%  
accuracy over load, line, temperature, and process.  
The device is stable with any type of capacitor  
greater than or equal to 2.2µF, and is fully specified  
from –40°C to +125°C. The TPS74701 is offered in a  
small 3mm × 3mm SON-10 package for compatibility  
with the TPS74801.  
Available in a Small 3mm × 3mm × 1mm
