DESCRIPTION
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.

LOW INPUT VOLTAGE, 1-A LOW-DROPOUT LINEAR REGULATORS WITH SUPERVISOR
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).
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.
Each
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
