3 Description
The TPS793 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
NanoStar™ wafer chip scale and SOT23 packages.
NanoStar packaging gives an ultrasmall footprint as
well as an ultralow profile and package weight,
making these devices 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 TPS793 family uses an
advanced, proprietary BiCMOS fabrication process to
yield extremely low dropout voltages (for example,
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 at 2.8-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 and low-noise features
as well as the fast response time.

DESCRIPTION
I
Enable pin. Driving the enable pin (EN) high turns on the regulator. Driving this pin low puts
the regulator into shutdown mode. EN can be connected to IN if not used.
I
Feedback pin. This terminal is the feedback input pin for the adjustable device. Fixed voltage
versions in the DBV package do not have this pin.
— Regulator ground.
I
Input to the device.
Noise Reduction pin. Connecting an external capacitor to this pin filters noise generated by
— the internal bandgap. This configuration improves power-supply rejection and reduces output
noise.
O Output of the regulator.
