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-μF 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 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 μV
of output voltage noise with a 0.1-μF bypass capacitor. Applications with analog
RMS
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.
