Its PSRR holds 80 dB at 10 Hz and rolls off to 64 dB at 100 kHz, which means upstream switching noise from a buck converter or charge pump gets attenuated by a factor of several thousand before reaching the load rail — useful for powering sensitive analog front-ends or RF oscillators where supply ripple directly modulates the signal. Maximum dropout is 200 mV at the full 350 mA load, so a 1.4 V input rail provides the needed headroom with margin across temperature. Quiescent current sits at 28 µA typical, with a maximum supply current of 100 µA — low enough that the regulator's own draw does not dominate the battery budget in always-on sensor nodes. ## 5-DSBGA package and board-fit realities Housed in a 5-bump DSBGA (5-WFBGA) measuring 1.41 x 1.08 mm, this is a wafer-level chip-scale package with no leads — the solder bumps are the entire interface. The 0.4 mm pitch and 0.5 mm nominal ball height mean the PCB land pattern must match the TI recommended footprint exactly; a 0.3 mm solder-mask-defined pad with a 0.25 mm solder-paste aperture is the usual starting point. The enable pin (active high) lets the system shut down the regulator when the load is idle — pulling it low drops the total draw to near zero, which matters for battery-powered products that spend most of their time in sleep. Protection includes over-current, over-temperature, short-circuit, and under-voltage lockout, so a downstream fault or a hot day does not cascade into a board failure.","metaTitle":"LP5952TL-1.2/NOPB LDO Regulator, 1.2V Fixed, 350mA, 5-DSBGA","metaDescription":"Texas Instruments LP5952TL-1.2/NOPB LDO regulator, fixed 1.2V output at 350mA. 80dB PSRR at 10Hz, 28µA Iq.
