This asymmetric current pairing is intentional — it suits designs where a low-current analog rail (1.8 V for PLLs, ADC reference, or I/O) coexists with a higher-current digital core or memory rail at 3.3 V, all from a single input up to 5.5 V. Quiescent current sits at 80 µA, which keeps standby draw low for battery-powered or always-on subsystems. Enable control on both regulators lets the system power down unused rails independently. ## PSRR and dropout — the two specs that decide your input rail PSRR is rated at 60 dB at 1 kHz, rolling off to 40 dB at 20 kHz. That roll-off matters if you are powering a sensitive analog front-end or a radio that draws current at switching frequencies above 1 kHz — the regulator still attenuates ripple, but the margin shrinks. For a 5 V input feeding the 3.3 V rail, the 0.42 V dropout at 300 mA leaves about 1.28 V headroom, which is comfortable. But if the input sags to 3.6 V during a cold-crank event, the 3.3 V rail has only 0.3 V of margin — the dropout spec becomes the binding constraint. The 1.8 V rail with its 0.25 V dropout at 150 mA is easier to satisfy from a 3.3 V intermediate bus. ## Package and thermal — the 10-MLF exposed pad is not optional The datasheet pad pattern expects a 3x3 mm solder area on the PCB with at least four thermal vias to the ground plane. Without those vias, the junction-to-board thermal resistance roughly doubles, and the 300 mA channel will hit thermal shutdown well below the 125 °C rated maximum in still air.","metaTitle":"MIC2211-GSYML-TR Dual LDO Regulator, 1.8V/3.3V Fixed Output","metaDescription":"MIC2211-GSYML-TR dual 150mA/300mA LDO with fixed 1.8V/3.3V outputs, PSRR 60dB~40dB (1kHz~20kHz), dropout 0.25V/0.42V max, -40°C to 125°C, 10-MLF.
