It is built for surface-mount assembly in the TO-252-3 (DPak) package, with the tab as the ground plane — heatsinking through the PCB copper is expected. The 50 µA quiescent current keeps standby draw low enough for battery-backed or always-on rails, while the 55 dB PSRR at 120 Hz gives reasonable line-frequency ripple rejection for powering analog front-ends or MCU supplies from a rectified bulk rail. ## Dropout and protection — what the numbers mean for the BOM Maximum dropout is 0.65 V at the full 500 mA load. The part includes over-current and over-temperature protection. ## Temperature grade and environment Rated for -40°C to 125°C operating junction temperature, this part fits industrial environments: motor drives, outdoor telecom, factory-floor sensors, and engine-bay electronics. The TO-252-3 package with the exposed tab allows the heat to be sunk into the board copper — a layout consideration for sustained 500 mA at high ambient. ## Sourcing and lifecycle It is RoHS non-compliant per the listing, so verify your assembly line's exemption or waiver if lead-free processing is required.","metaTitle":"LP8345IDTX-2.5 LDO Regulator, Fixed 2.5V, 500mA, TO-252-3","metaDescription":"LP8345IDTX-2.5 fixed 2.5V LDO regulator, 500mA output, 55dB PSRR, 50µA Iq, -40°C to 125°C.
