This is a positive-output LDO pair in a single 8-uDFN (2x2 mm) package — two independent rails for the footprint of one small IC. PSRR is the headline here: 60 dB at 1 kHz, rolling to 55 dB at 10 kHz. That means this LDO attenuates 1 kHz ripple from a switching pre-regulator by 1000×, but above 10 kHz the rejection drops — if your upstream switcher runs at 2 MHz, the PSRR at that frequency is lower than the 1 kHz figure, so you need to check the full curve. The 200 mV dropout at 100 mA per channel leaves headroom for a 2.85 V rail from a 3.3 V input. Quiescent current is 75 µA typical — low enough for always-on sensor supplies but not ultra-low-power; the enable pin lets you gate each regulator for sleep modes. ## Protection and temperature range for industrial use Built-in over-current, over-temperature, and undervoltage lockout (UVLO) protect the load and the regulator itself.","metaTitle":"Analog Devices MAX8634ELA+ Dual LDO, 2x300mA, 60dB PSRR","metaDescription":"MAX8634ELA+ dual 300 mA LDO, 60-55 dB PSRR, 2.6-2.85 V programmable output, 8-uDFN package, active production.
