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 TPS731xx family of low-dropout (LDO) linear voltage regulators uses a new topology: an NMOS pass

element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR and

even allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and

ground pin current that is nearly constant over all values of output current.

The TPS731xx uses an advanced BiCMOS process to yield high precision while delivering low dropout voltages

and low ground pin current. Current consumption, when not enabled, is under 1

μA and ideal for portable

applications. The low output noise (30

protected by thermal shutdown and foldback current limit.
