Quiescent current is 125 µA typical, which keeps the self-heating low in always-on rails. ## PSRR and noise rejection at line frequency Power-supply rejection ratio is specified at 60 dB at 100 Hz — this is the 2× line-frequency (100/120 Hz) ripple from a full-wave rectifier. A 60 dB rejection means the ripple on the input is attenuated by a factor of 1000 at that frequency, so a 100 mVpp ripple on the input rail becomes roughly 0.1 mVpp on the 3.3 V output. For sensitive analog loads like a pre-amp or ADC reference, that keeps the supply noise out of the signal band. ## Protection and control for unattended rails Built-in protection covers over-current, over-temperature, and reverse polarity on the input. The control features include an enable pin, a power-good flag, and a reset output — the power-good signal can sequence a downstream load or hold a microcontroller in reset until the 3.3 V rail is stable.","metaTitle":"TPS75433QPWP LDO Regulator, 3.3V Fixed, 2A, 20-HTSSOP","metaDescription":"Texas Instruments TPS75433QPWP LDO, 3.3V fixed output, 2A, 20-PowerTSSOP.
