TPS730xx www.ti.com SBVS054I NOVEMBER 2004 REVISED FEBRUARY 2011 LOW-NOISE, HIGH PSRR, RF 200-mA LOW-DROPOUT LINEAR REGULATORS Check for Samples: TPS730xx 1 FEATURES DESCRIPTION 234 200-mA RF Low-Dropout Regulator The TPS730xx family of low-dropout (LDO) With Enable low-power linear voltage regulators features high power-supply rejection ratio (PSRR), ultralow-noise, Available in Fixed Voltages from 1.8V to 3.3V fast start-up, and excellent line and load transient and Adjustable (1.22V to 5.5V) responses a small SOT23 package. NanoStar High PSRR (68dB at 100Hz) packaging gives an ultrasmall footprint as well as an Ultralow-Noise (33V , TPS73018) RMS ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. Fast Start-Up Time (50s) Each device in the family is stable, with a small 2.2F Stable With a 2.2F Ceramic Capacitor ceramic capacitor on the output. The TPS730xx Excellent Load/Line Transient Response family uses an advanced, proprietary BiCMOS fabrication process to yield low dropout voltages (e.g., Very Low Dropout Voltage (120mV at 200mA) 120mV at 200mA, TPS73030). Each device achieves 5- and 6-Pin SOT23 (DBV), and Wafer Chip fast start-up times (approximately 50s with a Scale (YZQ) Packages 0.001F bypass capacitor) while consuming low quiescent current (170A typical). Moreover, when APPLICATIONS the device is placed in standby mode, the supply RF: VCOs, Receivers, ADCs current is reduced to less than 1A. The TPS73018 exhibits approximately 33V of output voltage Audio RMS noise at 1.8V output with a 0.01F bypass capacitor. Cellular and Cordless Telephones Applications 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.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
