The 63 dB PSRR at 120 Hz knocks down rectified line ripple. Operating temperature spans -40°C to 125°C, so this part handles industrial cabinet heat and outdoor telecom enclosures without derating drama. The TO-263-6 D²Pak (5-lead plus tab) package means the exposed pad is the primary thermal path — board layout must mate that tab to a copper plane for the 1.5A continuous draw. ## Protection set and control Built-in over-current, over-temperature, and reverse-polarity protection cover the common failure modes: a shorted output won't cook the die, a hot environment won't let it run away, and a backwards battery connection won't kill it. The enable pin lets a supervisor or GPIO gate the rail — useful for sequencing multiple supplies at power-up or shutting down a sub-circuit in sleep mode. ## Active lifecycle — no LTB clock ticking Product status is Active per the manufacturer, and ROHS3 compliant. No last-time-buy notice, no end-of-life watch. This part can be specified into a production BOM without planning for an obsolescence migration.","metaTitle":"LT1963AEQ-1.5#PBF Linear Regulator, 1.5V Fixed, 1.5A, D²Pak","metaDescription":"LT1963AEQ-1.5#PBF from Analog Devices: 1.5V fixed-output LDO, 1.5A, 63dB PSRR at 120Hz, 0.55V dropout max.
