description

This device is designed to have a fast transient response and be stable with 10-µF low ESR capacitors. This

combination provides high performance at a reasonable cost.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 230 mV

at an output current of 1 A for the TPS76850) 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 85 µA over the full range of output current, 0 mA to 1 A). These two key specifications yield

a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep

mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to

less than 1 µA at T = 25°C.

Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery

indicator.

The TPS768xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and

in an adjustable version (programmable over the range of 1.2 V to 5.5 V). Output voltage tolerance is specified

as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP

package.

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.
