The 25 µA quiescent current and 350 µA max supply current keep the overhead low in always-on domains. ## PSRR across the switching band The PSRR starts at 80 dB at 100 Hz and rolls off to 25 dB at 2 MHz. This means the regulator attenuates low-frequency ripple well — 80 dB knocks a 10 mV ripple down to 1 µV — but above a few hundred kHz the rejection drops, so a downstream LDO or a pi-filter ahead of the input may be needed if the upstream switcher runs above 1 MHz. The 1 V output is fixed, so the BOM position is a drop-in rail for a 1 V core or I/O supply. ## Protection set and package Over-temperature, reverse polarity, and short-circuit protection are built in. The 4-DSBGA package is a 0.8 mm × 0.8 mm ball-grid array — the 4-ball footprint fits into tight floorplans but requires a controlled reflow profile and X-ray inspection post-solder. The enable pin lets the system shut the rail off, dropping the quiescent current to near zero in sleep states. Lifecycle status is active. The part is ROHS3 compliant.","metaTitle":"LP5910-1.0YKAR 300mA LDO, 1V Fixed, 4-DSBGA","metaDescription":"Texas Instruments LP5910-1.0YKAR linear regulator, 300mA output, 1V fixed, 80dB PSRR, -40 to 125°C.
