It is designed for applications where a clean, regulated low-voltage rail is needed from a 5.5 V maximum input — think sensor supplies, MCU analogue rails, or RF front-end bias lines. The PSRR holds 65 dB at 1 kHz and rolls to 42 dB at 20 kHz, so it rejects switching-regulator ripple across the audio band and into the low-MHz noise spectrum. That matters when the LDO sits downstream of a buck converter. ## Dropout and quiescent current — the BOM-fit numbers Maximum dropout is 0.2 V at the full 300 mA load. That means the input can drop to 1.7 V before the output falls out of regulation — useful on a 3.3 V bus or a single-cell Li-ion rail near end-of-discharge. Quiescent current is 120 µA typical, which keeps the battery drain low in always-on subsystems. The enable pin lets a system controller shut down the regulator entirely when the rail is not needed. Protection includes over-current and over-temperature shutdown — no external clamp diodes needed for the usual fault conditions. ## Package and temperature grade — where it fits It comes in a 4-TMLF package (1.2 mm x 1.6 mm) with an exposed pad for thermal dissipation. It is ROHS3 compliant.","metaTitle":"MIC5303-1.5YMT-TR LDO Regulator, 1.5V Fixed Output, 300mA","metaDescription":"MIC5303-1.5YMT-TR fixed-output LDO from Microchip: 1.5V at 300mA, PSRR 65dB~42dB (1kHz~20kHz), dropout 0.2V max.
