DESCRIPTION
The
TPS793xx
low-power linear voltage regulators features high
power-supply rejection ratio (PSRR), ultralow-noise,
fast start-up, and excellent line and load transient
responses in NanoStar wafer chip scale and SOT23
packages. NanoStar packaging gives an ultrasmall
footprint as well as an ultralow profile and package
weight, making it ideal for portable applications such
as handsets and PDAs. Each device in the family is
stable, with a small 2.2μF ceramic capacitor on the
output. The TPS793xx family uses an advanced,
proprietary BiCMOS fabrication process to yield
extremely low dropout voltages (for example, 112mV
at 200mA, TPS79330). Each device achieves fast
start-up times (approximately 50μs with a 0.001μF
bypass
capacitor)
quiescent current (170μA typical). Moreover, when
the device is placed in standby mode, the supply
current is reduced to less than 1μA. The TPS79328
exhibits approximately 32μV
noise at 2.8V output with a 0.1μF bypass capacitor.
Applications with
noise-sensitive, such as portable RF electronics,
benefit from the high PSRR and low-noise features
as well as the fast response time.

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 ...
