The TPS730 family of low-dropout (LDO) low-power linear voltage regulators features high power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses in a small SOT-23 package. 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, 2.2-µF ceramic capacitor on the output. The TPS730 family uses an advanced, proprietary BiCMOS fabrication process to yield low dropout voltages (for example, 120 mV at 200 mA, TPS73030). Each device achieves fast start-up times (approximately 50 µs with 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 current is reduced to less than 1 µA. The TPS73018 exhibits approximately 33 µVRMS of output voltage noise at 1.8 V output with a 0.01-µF 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.
