SBVS037F – AUGUST 2003 – REVISED SEPTEMBER 2004
The TPS732xx family of low-dropout (LDO) 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 TPS732xx uses an advanced BiCMOS process
to yield high precision while delivering very low
dropout voltages and low ground pin current. Current
consumption, when not enabled, is under 1µA and
ideal for portable applications. The extremely low
output noise (30µV
powering VCOs. These devices are protected by
thermal shutdown and foldback current limit.
RMS
with 0.1µF C
) is ideal for
NR
APPLICATIONS
• Portable/Battery-Powered Equipment
• Post-Regulation for Switching Supplies
• Noise-Sensitive Circuitry such as VCOs
• Point of Load Regulation for DSPs, FPGAs,
ASICs, and Microprocessors

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.
