† Component qualification in accordance with JEDEC and industry

standards to ensure reliable operation over an extended

temperature range. This includes, but is not limited to, Highly

Accelerated Stress Test (HAST) or biased 85/85, temperature

cycle, autoclave or unbiased HAST, electromigration, bond

intermetallic life, and mold compound life. Such qualification

testing should not be viewed as justifying use of this component

beyond specified performance and environmental limits.

Fixed-Output Versions

description

The TPS776xx devices are designed to have a fast transient response and be stable with a 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 169 mV at an

output current of 500 mA for the TPS77633) 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 500 mA). 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 1

Power good (PG) of the TPS776xx is an active high output, which can be used to implement a power-on reset or

a low-battery indicator.

The TPS776xx are offered in 1.5-V, 1.8-V, 2.5-V, 2.8 V, and 3.3-V fixed-voltage versions and in an adjustable version

(programmable over the range of 1.2 V to 5.5 V for TPS77601 option). Output voltage tolerance is specified as a

maximum of 2% over line, load, and temperature ranges. The TPS776xx family is available in 20 pin TSSOP

package.
