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 2.2-μF ceramic capacitor on the
output. The TPS793xx family uses an advanced,
proprietary BiCMOS fabrication process to yield ex-
tremely 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 quiesc-
ent 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 μV
RMS
of output voltage noise at
2.8-V output with a 0.1-μF bypass capacitor. Appli-
cations
with
analog
noise-sensitive, such as portable RF electronics,
benefit from the high PSRR and low-noise features
as well as the fast response time.
