The TPS793xx 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 in NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs. Each device in the family is stable, with a small 2.2F ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112mV at 200mA, TPS79330). Each device achieves fast start-up times (approximately 50s with a 0.001F bypass capacitor) while consuming very low quiescent current (170A typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1A. The TPS79328 exhibits approximately 32VRMS of output voltage noise at 2.8V output with a 0.1F bypass capacitor. Applications 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.
