The 70 dB PSRR at 1 kHz means switching noise from a buck converter upstream gets attenuated by a factor of 3000 before it reaches the load — important when powering a PLL or ADC reference that cannot tolerate ripple on the core supply. ## Quiescent discipline and protection Quiescent current sits at 140 µA typical, with a maximum supply draw of 90 µA — the regulator's own consumption stays low enough for battery-backed always-on domains in portable instrumentation or industrial sensors. Built-in protection covers over-current, over-temperature, and short-circuit conditions. The Enable and Reset control pins let a supervisor or MCU sequence the rail on and off, and monitor when the output is within regulation. ## Package and board-fit for field replacement ROHS3 compliant, no lead or restricted substances per the current exemption list.","metaTitle":"MAX1976AETA120+T LDO, 1.2V Fixed, 300mA, 70dB PSRR","metaDescription":"Analog Devices MAX1976AETA120+T linear regulator, fixed 1.2V output, 300mA, 70dB PSRR at 1kHz, 8-TDFN.
