It is built for surface-mount assembly in a 6-DFN 2x2 mm exposed-pad package. The 6 µA quiescent current and 1 mA maximum supply current keep the thermal budget tight on always-on circuits. Control via the Enable pin lets a supervisor or GPIO shut down the rail entirely, pulling Iq to near zero. Protection covers over-current, over-temperature, and reverse polarity — the reverse-polarity clamp is unusual at this current level and saves an external Schottky in single-supply portable designs. ## Temperature grade and deployment Rated for -40°C to 125°C operating junction temperature. That puts it in the industrial and automotive under-hood bracket — engine bay electronics, outdoor telecom enclosures, factory-floor sensor modules. The 6-DFN exposed pad requires a thermal via pattern under the package for heat spreading; the datasheet landing pattern is the reference, not a generic DFN footprint. ## Active lifecycle — no LTB risk The LT3009EDC-1.8#TRMPBF carries an Active product status with ROHS3 compliance. No last-time-buy notice, no end-of-life window. It is a current-production part suitable for new-design qualification and volume BOMs. Sourced through independent distribution; availability and current pricing confirmed at quote time against an RFQ.","metaTitle":"LT3009EDC-1.8#TRMPBF Linear Regulator, 1.8V 20mA, 6-DFN","metaDescription":"LT3009EDC-1.8#TRMPBF IC REG LINEAR 1.8V 20MA 6DFN from Analog Devices.
