Each device in the family is stable with a small, 1-μF ceramic capacitor on the output.
The family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (for example, 250 mV at 1 A).
Each device achieves fast start-up times (approximately 50 μs with a 0.
001-μF bypass capacitor) while consuming very low quiescent current (265 μA typical).
Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 μA.
The TPS79630 exhibits approximately 40 μVRMS of output voltage noise at 3.
0-V output, with a 0.
1-μF bypass capacitor.
