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 μVRMS of output voltage noise 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.
