The -40°C to 125°C operating range covers automotive under-hood and industrial motor-drive environments. ## Dropout and quiescent current — the real-world margins Maximum dropout is 0.58 V at the full 150 mA load. Quiescent current sits at 95 µA typical. The 16 V maximum input voltage lets this LDO survive load-dump transients. Over-current, over-temperature, and short-circuit protection are built in. ## Lifecycle and sourcing The LP2985-28DBVR carries an Active product status per the manufacturer. It is ROHS3 compliant. No last-time-buy or end-of-life notice is in effect.","metaTitle":"LP2985-28DBVR LDO Regulator, 2.8V Fixed Output, 150mA","metaDescription":"LP2985-28DBVR is an active 2.8V fixed-output LDO from TI, rated 150mA with 45dB PSRR at 1kHz.
