Input voltage maxes at 6 V. Dropout voltage maxes at 0.22 V at 200 mA. Quiescent current runs 270 µA typical. That is moderate for a 300 mA LDO — not the ultra-low-Iq tier for always-on battery gear, but fine for a powered sensor bus or a logic rail where the regulator is enabled only when the system is active. The enable pin (Control Features: Enable) lets a GPIO or supervisor IC gate the output, which saves power in multi-rail sequencing. Protection covers over-current, over-temperature, and reverse polarity on the input. Reverse polarity protection is a practical addition for field-installed equipment where a connector can be miswired — it saves an external series diode and its associated dropout. Operating temperature spans -40°C to 85°C, so the part is at home in industrial enclosures, outdoor telecom cabinets, and factory-floor control panels. ## Package and mounting — 8-WSON with exposed pad Mounting is surface mount. The Bulk shipping form means the parts arrive in a tube or tray, not on a reel — check your pick-and-place feeder compatibility if you are running high-volume assembly; a Tape & Reel variant may be needed for automated lines.","metaTitle":"LP3982ILD-1.8/NOPB LDO Regulator, 1.8V Fixed Output, 300mA","metaDescription":"Texas Instruments LP3982ILD-1.8/NOPB is a 300mA fixed-output LDO regulator delivering 1.8V from a max 6V input.

It is not a pin-compatible drop-in for the 1.8 V output; if you need 1.8 V, the TPS7A0218PYCHR is a 200 mA fixed 1.8 V LDO with under-voltage lockout and a lower quiescent current (60 nA typical), but it also has a different package and protection set.
