Surface-mount assembly; the tape-and-reel (TR) or cut-tape (CT) packaging options suit both prototype and production volumes. ## Regulator parametrics and the so-what This is a single-output positive LDO with a fixed 3.3 V output, delivering up to 300 mA continuous. The maximum dropout voltage is 0.15 V at full load — meaning the input rail needs to stay above 3.45 V to maintain regulation across the load range. With a quiescent current of 100 µA and a maximum supply current of 65 µA, the regulator's own draw is low enough for battery-powered designs where every microamp counts. ## PSRR and noise rejection The power-supply rejection ratio is 40 dB at 1 kHz. This means ripple on the input at 1 kHz is attenuated by a factor of 100 — a 100 mVpp input ripple becomes roughly 1 mVpp on the output. For analog front-ends or precision reference rails, this rejection drops at higher frequencies; above 100 kHz the LDO's loop gain rolls off, so upstream switching noise at those frequencies needs additional filtering ahead of the regulator. ## Protection and control features Built-in protection includes over-current, over-temperature, and short-circuit shut-down. The Enable pin allows the output to be gated by a logic signal — useful for sequencing multiple rails or powering down a subsystem to save leakage. The Power Good output flags when the output is within regulation, so a downstream load or supervisor can wait for the rail to settle before enabling. ## Temperature grade and operating envelope The part is not AEC-Q100 qualified, so it is not specified for under-hood or extended automotive temperature use. Analog Devices lists this part as Active in production. RoHS3 compliant.","metaTitle":"MAX8888EZK33+T LDO, 3.3V fixed, 300mA, TSOT-23-5","metaDescription":"Analog Devices MAX8888EZK33+T LDO regulator, 3.3V fixed output, 300mA, 40dB PSRR, TSOT-23-5.
