NanoStar™ packaging gives an ultrasmall footprint as well as an ultralow profile and • High PSRR (68 dB at 100 Hz) 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 uses an advanced, proprietary BiCMOS fabrication • Excellent Load/Line Transient Response 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 • 5- and 6-Pin SOT-23 (DBV), and Wafer Chip achieves fast start-up times (approximately 50 μs with Scale (YZQ) Packages 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 2 Applications current is reduced to less than 1 μA. The TPS73018 • RF: VCOs, Receivers, ADCs exhibits approximately 33 μVRMS of output voltage • Audio noise at 1.8 V output with a 0.01- μF bypass capacitor. Applications with analog components that • Cellular and Cordless Telephones are noise-sensitive, such as portable RF electronics, • Bluetooth®, Wireless LAN benefit from the high PSRR and low-noise features • Handheld Organizers, PDAs as well as the fast response time.
