TPS796xx
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 × 3 SON, SOT223-6,
and DDPAK-5 packages. Each device in the family is
stable with a small 1mF ceramic capacitor on the
output. The family uses an advanced, proprietary
BiCMOS fabrication process to yield extremely low
dropout voltages (for example, 250mV at 1A). Each
device achieves fast start-up times (approximately
50ms with a 0.001mF bypass capacitor) while
consuming very low quiescent current (265 mA
typical). Moreover, when the device is placed in
standby mode, the supply current is reduced to less
than 1mA. The TPS79630 exhibits approximately
40mV
of output voltage noise at 3.0V output, with
RMS
a 0.1mF 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.

    ... TPS796xx SLVS351N – SEPTEMBER 2002 – REVISED JANUARY 2011 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 ...
