description

V = 4.3 V

The TPS769xx family of low-dropout (LDO)

voltage regulators offers the benefits of low

dropout voltage, ultralow-power operation, and

miniaturized packaging. These regulators feature

low dropout voltages and ultralow quiescent

current compared to conventional LDO

regulators. Offered in a 5-terminal small outline

package,

the

TPS769xx series devices are ideal for

micropower operations and where board space is

at a premium.

= 0 mA

A combination of new circuit design and process

innovation has enabled the usual PNP pass

transistor to be replaced by a PMOS pass

element. Because the PMOS pass element

behaves as a low-value resistor, the dropout

voltage is very low, typically 71 mV at 100 mA of

– Free-Air Temperature – °C

load current (TPS76950), and is directly proportional to the load current. Since the PMOS pass element is a

voltage-driven device, the quiescent current is ultralow (28 µA maximum) and is stable over the entire range

of output load current (0 mA to 100 mA). Intended for use in portable systems such as laptops and cellular

phones, the ultralow-dropout voltage feature and ultralow-power operation result in a significant increase in

system battery operating life.

The TPS769xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current

to 1 µA typical at T = 25°C. The TPS769xx is offered in 1.2-V, 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V,

and 5-V fixed-voltage versions and in a variable version (programmable over the range of 1.2 V to 5.5 V).

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
