Qualification Pedigree

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.

Dual Output Voltages for Split-Supply

Applications

•

Output Current Range of 0 mA to 1.0 A Per

Regulator

•

3.3-V/Adjustable Output

•

Fast Transient Response

DESCRIPTION/ORDERING INFORMATION

The TPS767D301-EP dual-voltage regulator offers fast transient response, low dropout (LDO) voltages, and dual

outputs in a compact package and incorporates stability with 10-mF low-ESR output capacitors.

The TPS767D301-EP dual-voltage regulator is designed primarily for DSP applications. This device can be used

in any mixed-output voltage application, with each regulator supporting up to 1 A. Dual active-low reset (RESET)

signals allow resetting of core logic and I/O separately.
