FEATURES  
DESCRIPTION  
D
Qualified For Automotive Applications  
ESD Protection Exceeds 2000 V Per  
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

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.
