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.

Typical Application Circuit for Fixed-Voltage Versions
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
