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.

DESCRIPTION/ORDERING INFORMATION
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 μV_RMS with 0.1 μF C_NR) is ideal for powering VCOs. These devices are
protected by thermal shutdown and foldback current limit.
