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 very low
dropout voltages and low ground pin current. Current
consumption, when not enabled, is under 1mA and
ideal for portable applications. The extremely low
output noise (30mV
powering VCOs. These devices are protected by
thermal shutdown and foldback current limit.

    ... TPS732xx SBVS037O – AUGUST 2003 – REVISED AUGUST 2010 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 ...
