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.
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 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
Although an output capacitor is not required for stability, transient response and output noise are improved with a
10-µF output capacitor.
Unlike some regulators that have a minimum current requirement, the TPS725 family is stable with no output
load current. The low noise capability of this family, coupled with its high current operation and ease of power
dissipation, make it ideal for telecom boards, modem banks, and other noise-sensitive applications.

This terminal is the feedback point for the adjustable option TPS72501. For all other options, this
terminal is the RESET output terminal. When used with a pullup resistor, this open-drain output
provides the active low RESET signal when the regulator output voltage drops more than 5% below
its nominal output voltage. The RESET delay time is typically 50 ms.
