FEATURES  
DESCRIPTION  
2
100-mA Low-Dropout Regulator With EN  
Available in 1.8-V, 3.3-V, 4.7-V, and Adjustable  
Versions  
The TPS791xx 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 1-µF  
ceramic capacitor on the output. The family uses an  
advanced, proprietary BiCMOS fabrication process to  
yield extremely low dropout voltages (e.g., 38 mV at  
100 mA, TPS79147). Each device achieves fast  
start-up times (approximately 63 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 TPS79118  
exhibits approximately 15 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.
