Its headline spec is 75 dB of power-supply rejection at 120 Hz — the ripple frequency from a full-wave rectified mains supply. That means the output sees roughly one ten-thousandth of the input ripple at that frequency, which is enough to keep a sensitive analog front-end (ADC reference, op-amp supply, sensor bias) clean in a mixed-signal design running off a lightly filtered DC rail. ## Dropout headroom and thermal budget Maximum dropout is 1.3 V at the full 800 mA load. Below that headroom the output falls out of regulation.","metaTitle":"TLV1117-18IDCYR LDO Regulator, 1.8V Fixed, 800mA, SOT-223","metaDescription":"Texas Instruments TLV1117-18IDCYR LDO, 1.8V fixed output, 800mA, 75dB PSRR at 120Hz.
