(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over specified
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

DESCRIPTION
The TPS793xx family of low-dropout (LDO)
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 a small-outline SOT23 package. Each
device in the family is stable, with a small 2.2-µF
ceramic capacitor on the output. The TPS793xx
family uses an advanced, proprietary, BiCMOS
fabrication process to yield extremely low dropout
voltages (e.g., 112 mV at 200 mA, TPS79330). Each
device achieves fast start-up times (approximately
50 µs with a 0.001-µF bypass capacitor), while
consuming very low quiescent current (170 µA
typical). Moreover, when the device is placed in
standby mode, the supply current is reduced to less
than 1 µA. The TPS79328 exhibits approximately
32 µVRMS of output voltage noise with a 0.1-µF
bypass capacitor. Applications with analog
components that are noise sensitive, such as
portable RF electronics, benefit from the high PSRR
and low-noise features, as well as the fast response
time.
