description

The TPS779xx is a low dropout regulator with

integrated power-on reset. The device is capable

of supplying 250 mA of output current with a

dropout of 200 mV (TPS77930). Quiescent

current is 92 µA at full load dropping down to 1 µA

when the device is disabled. The device is

optimized to be stable with a wide range of output

capacitors including low ESR ceramic (10 µF) or

low capacitance (1 µF) tantalum capacitors. The

device has extremely low noise output perfor-

mance (55 µV ) without using any added filter

capacitors. TPS779xx is designed to have a fast

transient response for larger load current

changes.

The TPS779xx is offered in 1.8-V, 2.5-V, and 3-V fixed-voltage versions and in an adjustable version

(programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature

ranges. The TPS779xx family is available in 8-pin MSOP (DGK) packages.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 200 mV

at an output current of 250 mA for 3.3 volt option) and is directly proportional to the output current. Additionally,

since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent

of output loading (typically 92 µA over the full range of output current, 0 mA to 250 mA). These two key

specifications yield a significant improvement in operating life for battery-powered systems.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

This document contains information on products in more than one phase

of development. The status of each device is indicated on the page(s)

specifying its electrical characteristics.
