SBVS065E–DECEMBER 2005–REVISED MAY 2007  
1.5A Ultra-LDO with Programmable Sequencing  
FEATURES  
DESCRIPTION  
•
•
•
Track Pin Allows for Flexible Power-Up  
Sequencing  
The TPS74301 low-dropout (LDO) linear regulator  
provides an easy-to-use robust power management  
solution for a wide variety of applications. The  
TRACK pin allows the output to track an external  
supply. This feature is useful in minimizing the stress  
on ESD structures that are present between the  
CORE and I/O power pins of many processors. The  
enable input and power-good output allow easy  
sequencing with external regulators. This complete  
flexibility allows the user to configure a solution that  
meets the sequencing requirements of FPGAs,  
DSPs, and other applications with special start-up  
requirements.  
1% Accuracy Over Line, Load, and  
Temperature  
Supports Input Voltages as Low as 0.9V with  
External Bias Supply  
•
•
•
•
•
Adjustable Output (0.8V to 3.6V)  
Ultra-Low Dropout: 55mV at 1.5A (typ)  
Stable with Any or No Output Capacitor  
Excellent Transient Response  
Available in 5mm × 5mm × 1mm QFN and  
DDPAK-7 Packages  
A precision reference and error amplifier deliver 1%  
accuracy over load, line, temperature, and process.  
Each LDO is stable with low-cost ceramic output  
capacitors and the device is fully specified from  
–40°C to +125°C. The TPS74301 is offered in a  
small (5mm × 5mm) QFN package, yielding a highly  
compact total solution size. For applications that  
require additional power dissipation, the DDPAK  
(KTW) package is also available.
