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

• 1-A Output Current

The TPS725xx family of 1-A low-dropout (LDO) linear

regulators has fixed voltage options available that are

• Available in 1.5-V, 1.6-V, 1.8-V, 2.5-V

commonly used to power the latest DSPs, FPGAs,

Fixed-Output and Adjustable Versions

and microcontrollers. An adjustable option ranging

(1.2-V to 5.5-V)

from 1.22 V to 5.5 V is also available. The integrated

• Input Voltage Down to 1.8 V

supervisory circuitry provides an active low RESET

• Low 170-mV Dropout Voltage at 1 A

signal when the output falls out of regulation. The no

(TPS72525)

capacitor/any capacitor feature allows the customer

to tailor output transient performance as needed.

• Stable With Any Type/Value Output Capacitor

Therefore, compared to other regulators capable of

• Integrated Supervisor (SVS) With 50-ms

providing the same output current, this family of

RESET Delay Time

regulators can provide a stand-alone power supply

• Low 210-µA Ground Current at Full Load

solution or a post regulator for a switch mode power

supply.

(TPS72525)

• Less than 1-µA Standby Current

These regulators are ideal for higher current appli-

cations. The family operates over a wide range of

• ±2% Output Voltage Tolerance Over Line,

input voltages (1.8 V to 6 V) and has very low

Load, and Temperature (-40°C to 125°C)

dropout (170 mV at 1-A).

• Integrated UVLO

Ground current is typically 210 µA at full load and

• Thermal and Overcurrent Protection

drops to less than 80 µA at no load. Standby current

• 5-Lead SOT223-5 or DDPAK and 8-Pin SOP

is less than 1 µA.

(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

• PCI Cards

package, the regulator dissipates more power and

• Modem Banks

achieves higher efficiencies than similar regulators

• Telecom Boards requiring 2.5 V or more minimum input voltage and

higher quiescent currents. These features make it a

• DSP, FPGA, and Microprocessor Power

viable power supply solution for portable, bat-

Supplies

tery-powered equipment.

• Portable, Battery-Powered Applications

NOTE: TPS72501 replaces RESET with FB. Tab is GND for the DCK and KTT packages.

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.

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.
