It is designed for powering analog and RF sections where supply ripple couples into the signal path — the PSRR holds 70 dB at 10 kHz and 54 dB at 100 kHz, so switching converter noise above 10 kHz sees meaningful attenuation before reaching the load. ## Quiescent current and protection set Quiescent current is 290 µA typical per regulator — modest for a dual LDO but not ultra-low-power; the part suits always-on rails where the load current dominates the system budget. Each output is protected against over-current, over-temperature, and short-circuit events, which matters when the regulator feeds a downstream DC-DC or a sensor that can short on the board. The Enable control pin lets each regulator be sequenced independently — useful when core and I/O rails must ramp in a defined order.","metaTitle":"MAX8559ETA88+ Dual 300mA LDO, 1.5V Fixed, PSRR 70dB","metaDescription":"Analog Devices MAX8559ETA88+ dual 300mA LDO, fixed 1.5V outputs, 6.5V input, 290µA Iq, PSRR 70-54dB, -40°C to +85°C, 8-TDFN.
