LOW INPUT VOLTAGE, 1-A LOW-DROPOUT LINEAR REGULATORS WITH SUPERVISOR  
FEATURES  
DESCRIPTION  
1-A Output Current  
The TPS725xx family of 1-A low-dropout (LDO) linear  
regulators has fixed voltage options available that are  
commonly used to power the latest DSPs, FPGAs,  
and microcontrollers. An adjustable option ranging  
from 1.22 V to 5.5 V is also available. The integrated  
supervisory circuitry provides an active low RESET  
signal when the output falls out of regulation. The no  
capacitor/any capacitor feature allows the customer  
to tailor output transient performance as needed.  
Therefore, compared to other regulators capable of  
providing the same output current, this family of  
regulators can provide a stand-alone power supply  
solution or a post regulator for a switch mode power  
supply.  
Available in 1.5-V, 1.6-V, 1.8-V, 2.5-V  
Fixed-Output and Adjustable Versions  
(1.2-V to 5.5-V)  
Input Voltage Down to 1.8 V  
Low 170-mV Dropout Voltage at 1 A  
(TPS72525)  
Stable With Any Type/Value Output Capacitor  
Integrated Supervisor (SVS) With 50-ms  
RESET Delay Time  
Low 210-µA Ground Current at Full Load  
(TPS72525)  
Less than 1-µA Standby Current  
These regulators are ideal for higher current appli-  
cations. The family operates over a wide range of  
input voltages (1.8 V to 6 V) and has very low  
dropout (170 mV at 1-A).  
±2% Output Voltage Tolerance Over Line,  
Load, and Temperature (-40°C to 125°C)  
Integrated UVLO  
Ground current is typically 210 µA at full load and  
drops to less than 80 µA at no load. Standby current  
is less than 1 µA.  
Thermal and Overcurrent Protection  
5-Lead SOT223-5 or DDPAK and 8-Pin SOP  
(TPS72501 only) Surface Mount Package  
Each regulator option is available in either  
a
SOT223-5, D (TPS72501 only), or DDPAK package.  
With a low input voltage and properly heatsinked  
package, the regulator dissipates more power and  
achieves higher efficiencies than similar regulators  
requiring 2.5 V or more minimum input voltage and  
higher quiescent currents. These features make it a  
viable power supply solution for portable, bat-  
tery-powered equipment.
