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. Each device in  
the family is stable, with a small 2.2-µF ceramic  
capacitor on the output. The TPS730xx family uses  
an advanced, proprietary BiCMOS fabrication pro-  
cess to yield low dropout voltages (e.g., 120 mV at  
200 mA, TPS73030). Each device achieves fast  
start-up times (approximately 50 µs with a 0.001-µF  
bypass capacitor) while consuming 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 TPS73018 exhibits  
approximately 23 µVRMS of output voltage noise at  
2.8-V output with a 0.01-µF bypass capacitor. Appli-

High PSRR (68dB at 1 kHz)  
Ultralow-Noise (23 µVRMS, TPS73018)  
Fast Start-Up Time (50 µs)  
Stable With a 2.2-µF Ceramic Capacitor  
Excellent Load/Line Transient Response  
Very Low Dropout Voltage (120 mV at Full  
Load)

RF: VCOs, Receivers, ADCs  
Audio  
Cellular and Cordless Telephones  
Bluetooth®, Wireless LAN  
Handheld Organizers, PDAs  
cations 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.
