说明

The TPS730xx 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 a small SOT23 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 2.2µF ceramic capacitor on the output. The TPS730xx family uses an advanced, proprietary BiCMOS fabrication process to yield low dropout voltages (e.g., 120mV at 200mA, TPS73030). Each device achieves fast start-up times (approximately 50µs with a 0.001µF bypass capacitor) while consuming low quiescent current (170µA typical).
