Its 0.1 V maximum dropout at full load means the input rail can dip as low as 4.9 V before the output falls out of regulation — a tight headroom that suits battery-powered gear where every millivolt of margin counts. ## PSRR profile and noise rejection PSRR is specified at 50 dB at 1 kHz, dropping to 40 dB at 10 kHz. This means the regulator attenuates low-frequency ripple from a switching pre-regulator by a factor of ~300 at 1 kHz, but the rejection weakens above a few kilohertz. For an analog front-end drawing 150 mA, the output noise floor will be dominated by the upstream switcher's switching frequency and its harmonics — a post-filter LC stage may be needed if the load is a sensitive ADC or PLL supply. Built-in protection covers over-current, over-temperature, and short-circuit events. The enable pin lets the system power down the regulator without disconnecting the input rail, reducing quiescent draw to near zero when the load is idle. ## Package and board-fit realities The 5-DSBGA package measures 1.41 x 1.08 mm — a wafer-level chip-scale package with no molded body. The solder balls are the only standoff; coplanarity is excellent but the package is moisture-sensitive. The tiny footprint demands a fine-pitch stencil and tight placement accuracy; a 0.4 mm aperture is typical for the 5-ball array. The 150 µA quiescent current and 250 µA max supply current keep the self-heating low even at high ambient. It is ROHS3 compliant, free of the ten restricted substances under EU RoHS.","metaTitle":"Texas Instruments LP3985ITL-4.8/NOPB LDO, 4.8V, 150mA","metaDescription":"Texas Instruments LP3985ITL-4.8/NOPB LDO fixed 4.8V output, 150mA, 0.1V dropout, PSRR 50-40dB, -40°C to 125°C, active production.
