NanoStar packaging gives an ultrasmall • Ultralow-Noise (32 µVRMS, TPS79328) footprint as well as an ultralow profile and package weight, making it ideal for portable applications such • Fast Start-Up Time (50 µs) as handsets and PDAs. Each device in the family is • Stable With a 2.2-µF Ceramic Capacitor stable, with a small 2.2-µF ceramic capacitor on the • Excellent Load/Line Transient Response output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield ex- • Very Low Dropout Voltage (112 mV at Full tremely low dropout voltages (e.g., 112 mV at Load, TPS79330) 200 mA, TPS79330). Each device achieves fast • 5- and 6-Pin SOT23 (DBV) and NanoStar Wafer start-up times (approximately 50 µs with a 0.001-µF Chip Scale (YEQ) Packages bypass capacitor) while consuming very low quiesc- ent current (170 µA typical). Moreover, when the device is placed in standby mode, the supply current • RF: VCOs, Receivers, ADCs is reduced to less than 1 µA. The TPS79328 exhibits approximately 32 µVRMS of output voltage noise at • Audio 2.8-V output with a 0.1-µF bypass capacitor. Appli- • Cellular and Cordless Telephones cations with analog components that are • Bluetooth™, Wireless LAN noise-sensitive, such as portable RF electronics, • Handheld Organizers, PDAs benefit from the high PSRR and low-noise features as well as the fast response time.
