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, BiCMOS fabrication process to yield extremely low dropout voltages (for example, 112 mV at 200 mA, 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.
