Each TPS793-Q1 device in the family is stable, with a small 2.2-μF ceramic capacitor on the output. The TPS793xx-Q1 family uses an advanced, proprietary, Bi CMOS fabrication process to yield extremely low dropout voltages (for example, 112 m V at 200 m A, TPS79330-Q1). Each device achieves fast start-up times (approximately 50 μs with a 0.001-μF bypass capacitor), while consuming very 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 TPS79328-Q1 exhibits approximately 32 μVRMS of output voltage noise with a 0.1-μF bypass capacitor. Applications with analog ponents that are noise sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise...
