8.1.3 Output Noise
The TPS7A53A-Q1 provides low output noise when a soft-start capacitor is used. When the device reaches the end of the soft-start cycle, the soft-start capacitor serves as a filter for the internal reference. By using a 10-nF, soft-start capacitor, the output noise is reduced by half and is typically 7.1 μVRMS for a 1-V output (10 Hz to 100 kHz). Further increasing CSS has little effect on noise. Because most of the output noise is generated by the internal reference, the noise is a function of the set output voltage. Equation 3 gives the RMS noise with a 10-nF, soft-start capacitor:
The low output noise makes this LDO a good choice for powering transceivers, phase-locked loops (PLLs), or other noise-sensitive circuitry.
