(1) 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.  
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 μVRMS with 0.1 μF CNR) is ideal for powering VCOs. These devices are  
protected by thermal shutdown and foldback current limit.
