The TPS732xx family of lowdropout (LDO) voltage regulators uses a new topology: an NMOS pass element in a voltagefollower 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 µVRMS with 0.1 µF CNR) is ideal for powering VCOs. These devices are protected by thermal shutdown and foldback current limit.
(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.
