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- µ F
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 µ s with a 0.001- µ F bypass capacitor), while
consuming very low quiescent current (170 µ A
typical). Moreover, when the device is placed in
standby mode, the supply current is reduced to less
than 1 µ A. The TPS79328 exhibits approximately
32 µ V
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
of output voltage noise with a 0.1- µ F
RMS

I/O DESCRIPTION
An external bypass capacitor, connected to this terminal, in conjunction with an internal
resistor, creates a low-pass filter to further reduce regulator noise.
Enable input that enables or shuts down the device. When EN goes to a logic high, the
device is enabled. When the device goes to a logic low, the device is in shutdown mode.
