DESCRIPTION
The
TPS796xx
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 small outline, 3 x 3 SON, SOT223-6,
and 5-pin DDPAK packages. Each device in the
family is stable with a small 1-μF ceramic capacitor
on the output. The family uses an advanced, pro-
prietary BiCMOS fabrication process to yield ex-
tremely low dropout voltages (e.g., 250 mV at 1 A).
Each
device
achieves
(approximately 50 μs with a 0.001-μF bypass capaci-
tor) while consuming very low quiescent current
(265 μA typical). Moreover, when the device is placed
in standby mode, the supply current is reduced to
less than 1 μA. The TPS79630 exhibits approximately
40 μV
RMS
of output voltage noise at 3.0-V output, 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, low
noise features, and the fast response time.
