1• 200-mA RF Low-Dropout Regulator
With linear voltage regulators features high power-supply Enable rejection ratio (PSRR), low noise, fast start-up, and
• Available in Fixed Voltages from 1.8 V to 3.3 V excellent line and load transient responses in a small
and Adjustable Voltages (1.22 V to 5.5 V) SOT-23 package. NanoStar™ packaging gives an
• High PSRR (68 dB at 100 Hz) ultrasmall footprint as well as an ultralow profile and
package weight, making it ideal for portable • Low Noise (33 μVRMS, TPS73018)
applications such as handsets and PDAs. Each
• Fast Start-Up Time (50 μs) device in the family is stable, with a small, 2.2-μF
• Stable With a 2.2-μF Ceramic Capacitor ceramic capacitor on the output. The TPS730 family
• Excellent Load/Line Transient Response uses an advanced, proprietary BiCMOS fabrication
process to yield low dropout voltages (for example,
• Very Low Dropout Voltage (120 mV at 200 mA) 120 mV at 200 mA, TPS73030). Each device
