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

FEATURES

DESCRIPTION

•

1-A Low-Dropout Regulator Supports Input

Voltages Down to 1.8-V

The TPS726xx 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. The integrated supervisory

circuitry provides an active low RESET signal when

the output falls out of regulation. The no capaci-

tor/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 1.26-V, 1.5-V, 1.6-V, 1.8-V, 2.5-V,

and Adjustable (1.22-V to 5.5-V)

•

Stable With Any Type/Value Output Capacitor

±2% Output Voltage Tolerance Over Line,

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

•

Integrated Supervisor (SVS) With 200-ms

RESET Delay Time

Low 170-mV Dropout Voltage at 1 A

(TPS72625)

These regulators operate over a wide range of input

voltages (1.8 V to 6 V) and have 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.

•

Low 210-µA Ground Current at Full Load

Less than 1-µA Standby Current

Integrated UVLO with Thermal and

Overcurrent Protection

•

5-Lead SOT223-5 or DDPAK Surface-Mount

Package

Unlike some regulators that have a minimum current

requirement, the TPS726xx 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.

APPLICATIONS

•

PCI Cards

Modem Banks and Telecom Boards

DSP, FPGA, and Microprocessor Power

Supplies

Portable, Battery-Powered Applications

1.26-V Core Voltage for the Following DSPs:

– TMS320vC5501

The TPS726xx is available in either a SOT223-5 or

DDPAK package. The TPS726126 is available in a

SOT223-5 package only.
