(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.
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

DESCRIPTION
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 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.
