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.

The TPS77401 is a low-dropout (LDO) regulator with power good (PG) function. This device is capable of

supplying 250 mA of output current with a dropout of 200 mV. Quiescent current is 92

µA at full load dropping

down to 1

µA when device is disabled. This 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. This device has

extremely low noise output performance (55

µV

designed to have fast transient response for larger load current changes.

The TPS77401 is offered in 1.5-V, 1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5-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 TPS77401 device is available in an 8-pin mini small-outline package (MSOP)

(DGK).
