ULTRALOW-NOISE, HIGH PSRR, FAST RF 500-mA  
LOW-DROPOUT LINEAR REGULATORS  
FEATURES  
DESCRIPTION  
•
500-mA Low-Dropout Regulator With Enable  
The TPS795xx 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, SOT223-6, package.  
Each device in the family is stable with a small 1-µF  
ceramic capacitor on the output. The family uses an  
advanced, proprietary BiCMOS fabrication process to  
yield extremely low dropout voltages (for example,  
110 mV at 500 mA). Each device achieves fast  
start-up times (approximately 50 µs with a 0.001-µF  
bypass capacitor) while consuming very low quiesc-  
ent current (265 µA typical). Moreover, when the  
device is placed in standby mode, the supply current  
is reduced to less than 1 µA. The TPS79530 exhibits  
approximately 33 µVRMS of output voltage noise at  
3.0 V output with a 0.1-µF bypass capacitor. Appli-  
cations with analog components that are noise sensi-  
tive, such as portable RF electronics, benefit from the  
high PSRR and low noise features, as well as the fast  
response time.
