Quiescent current sits at 55 µA, which keeps always-on microcontroller or sensor rails alive without draining the battery. ## PSRR profile — where it helps and where it doesn't PSRR measures 80 dB at 100 Hz and rolls off to 40 dB at 100 kHz. That means this LDO aggressively rejects 50/60 Hz mains ripple and its harmonics, which is exactly what a sensitive analog front-end or audio codec needs on its supply rail. Above 100 kHz — switching regulator ripple, for instance — the rejection drops to 40 dB, so plan on a post-filter capacitor or a second LDO stage if your noise budget is tight at those frequencies. ## Protection set for field survival Over-temperature shutdown, reverse polarity protection, and short-circuit current limiting are built in. If a board gets miswired or a load shorts, the regulator shuts down rather than letting the smoke out. The enable pin lets a system controller sequence the rail on and off; the power-good output signals when the output is within regulation, which simplifies reset generation for the downstream MCU or FPGA.","metaTitle":"LP5912-3.0DRVR LDO Regulator, 3V Fixed Output, 500mA, 6-WSON","metaDescription":"Texas Instruments LP5912-3.0DRVR is a 500mA fixed 3V LDO with 80dB PSRR at 100Hz, 55µA Iq, 0.25V max dropout.
