That 56 dB means ripple from a full-wave rectifier (100/120 Hz) is attenuated by a factor of roughly 630 — a 1 Vpp input ripple becomes about 1.6 mVpp on the output. For a 1.8 V rail feeding an analog front-end or a precision reference, that keeps the supply noise out of the signal passband. ## Dropout and headroom at full load Maximum dropout is 285 mV at 100 mA output. That sets the minimum input voltage at 2.085 V for a regulated 1.8 V rail at full current — a 3.3 V rail has 1.2 V of headroom, but a 1.8 V input rail would be marginal. The 250 µA quiescent current (Iq) is moderate; it's not a nanopower part, but for a 100 mA LDO the Iq-to-output ratio is under 0.3% at full load. ## Protection and control for a power rail On-chip protection covers over-current, over-temperature, and reverse polarity — the three common failure modes when a power rail gets miswired or shorted. The Enable pin lets a supervisor or GPIO sequence the rail on/off, which is useful for power-sequencing FPGAs or keeping a sensor supply off during sleep.","metaTitle":"LT3020EDD-1.8#PBF LDO Regulator, 100 mA, 1.8 V Fixed","metaDescription":"Analog Devices LT3020EDD-1.8#PBF linear regulator: 100 mA output, fixed 1.8 V, 56 dB PSRR at 120 Hz, 285 mV dropout.
