Product details

PSRR profile across frequency

The power-supply rejection ratio is specified at 80dB from 10Hz, rolling off to 50dB at 100kHz. That tells the designer where the regulator attenuates input ripple: strong rejection in the audio and line-frequency range, with moderate rejection through the switching-regulator band. If the upstream supply is a noisy DC-DC converter switching at 500kHz, the rejection at that frequency will be lower than the 50dB floor — the PSRR curve in the datasheet shows the full frequency response.

Frequently asked questions

Can TLV7111333DDSER be used with 5V input?

Yes. The maximum input voltage is 5.5V, so a 5V nominal supply is within range. With the 3.3V output, the 1.7V headroom is well above the 0.2V dropout requirement.

What is the PSRR of TLV7111333DDSER?

PSRR is specified at 80dB at 10Hz, decreasing to 50dB at 100kHz. This shows strong low-frequency rejection with moderate attenuation through the switching-regulator frequency range.
