DESCRIPTION  
Very Low Dropout Voltage  
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  
(112 mV at Full Load, TPS79330)
