LOW INPUT VOLTAGE, 1-A LOW-DROPOUT LINEAR REGULATORS WITH SUPERVISOR
1-A Low-Dropout Regulator Supports Input
The TPS726xx family of 1-A low-dropout (LDO) linear
Voltages Down to 1.8-V
regulators has fixed voltage options available that are
commonly used to power the latest DSPs, FPGAs,
Available in 1.26-V, 1.5-V, 1.6-V, 1.8-V, 2.5-V,
and microcontrollers.
The

tor/any capacitor feature allows the customer to tailor
Load, and Temperature (–40°C to 125°C)
output transient performance as needed. Therefore,
compared to other regulators capable of providing the

regulator for a switch mode power supply.
(TPS72625)
These regulators operate over a wide range of input
Low 210-A Ground Current at Full Load
voltages (1.8 V to 6 V) and have very low dropout
Less than 1-A Standby Current
(170 mV at 1-A). Ground current is typically 210 A at
full load and drops to less than 80 A at no load.
Integrated UVLO with Thermal and
Standby current is less than 1 A.
Overcurrent Protection
5-Lead SOT223-5 or DDPAK Surface-Mount
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.
DSP, FPGA, and Microprocessor Power
The TPS726xx is available in either a SOT223-5 or
Supplies
DDPAK package. The TPS726126 is available in a
Portable, Battery-Powered Applications
SOT223-5 package only.
1.26-V Core Voltage for the Following DSPs:
– TMS320vC5501
– TMS320vC5502
