100-mA Low-Dropout Regulator With EN  
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  
Available in 1.8-V, 3.3-V, 4.7-V, and Adj.

TPS79118 exhibits approximately 15 µV  
of  
RMS  
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.
