The fixed output eliminates the external resistor divider, saving two components and one feedback-node noise path on the board. ## Protection set and quiescent draw Built-in over-current, over-temperature, and short-circuit protection mean the regulator survives a sustained output short or a thermal event without external crowbar circuitry. The 9 mA quiescent current is the standing draw when the output is enabled; the Enable pin (active-high logic input) lets a system controller shut down the regulator to near-zero leakage when the 1.8 V rail is not needed. ## Temperature grade and package fit The SOT-223-5 (TO-261-5) surface-mount package has a large centre tab that conducts heat to the board copper; the datasheet's thermal-resistance figure assumes a minimum pad area, so the board layout determines the actual current derating above 85°C ambient.","metaTitle":"LP3962EMPX-1.8/NOPB Texas Instruments LDO, 1.5A, 1.8V Fixed","metaDescription":"Texas Instruments LP3962EMPX-1.8/NOPB fixed 1.8V LDO regulator, 1.5A output, 0.55V max dropout at full load.
