FEATURES  
DESCRIPTION  
2
•
Ultra-Low VIN and VOUT Range: 0.8V to 5.5V  
The TPS749xx low-dropout (LDO) linear regulator  
provides an easy-to-use robust power management  
•
•
•
VBIAS Range: 2.7V to 5.5V  
Low Dropout: 120mV (typ) at 3.0A, 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  
≥ 2.2μF, and the device is fully specified from –40°C  
to +125°C. The TPS749xx is offered in a small (5mm  
× 5mm) QFN package, yielding a highly compact total  
solution size. It is also available in a DDPAK-7.  
Available in 5mm × 5mm × 1mm QFN and  
DDPAK-7 Packages
