FEATURES  
DESCRIPTION  
•
200-mA RF Low-Dropout Regulator  
With Enable  
The TPS730xx 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 a small SOT23 package. NanoStar™  
packaging gives an ultrasmall footprint as well as an  
ultralow profile and package weight, making it ideal  
for portable applications such as handsets and  
PDAs. Each device in the family is stable, with a  
small 2.2µF ceramic capacitor on the output. The  
TPS730xx family uses an advanced, proprietary  
BiCMOS fabrication process to yield low dropout  
voltages (e.g., 120mV at 200mA, TPS73030). Each  
device achieves fast start-up times (approximately

a 0.001µF bypass capacitor) while  
consuming low quiescent current (170µA typical).  
Moreover, when the device is placed in standby  
mode, the supply current is reduced to less than  
1µA. The TPS73018 exhibits approximately 23µVRMS  
of output voltage noise at 2.8V output with a 0.01µF
