The Enable pin lets the system power down the regulator when the load is idle — useful for sequencing or reducing quiescent draw in a multi-rail design. ## Package and temperature grade Housed in the SOT-223-5 (TO-261-5 / TO-261AB) surface-mount package, this LDO fits a standard footprint shared by many medium-current regulators. The -40°C to 125°C operating range covers industrial and automotive ambient conditions — the tab is the thermal path; board copper area under it sets the effective RθJA.","metaTitle":"LP3965EMP-3.3 Texas Instruments LDO, 1.5 A Fixed 3.3 V","metaDescription":"Texas Instruments LP3965EMP-3.3 fixed-output LDO, 1.5 A, 0.55 V dropout max at full load, -40°C to 125°C, SOT-223-5.
