Product details

Fixed 1.5V rail, 1.5A capability — what it covers

The LT1963AEQ-1.5#PBF is a positive fixed-output LDO delivering 1.5V at up to 1.5A from a 20V max input rail. The 63 dB PSRR at 120 Hz knocks down rectified line ripple.

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.

No last-time-buy notice, no end-of-life watch.

Frequently asked questions

Is LT1963AEQ-1.5#PBF obsolete or nearing end of life?

No — the manufacturer lists this part as Active with no end-of-life notice. It can be specified into new designs without obsolescence risk.

What components can replace LT1963AEQ-1.5#PBF if not available?

The LT1963AES8-1.5#PBF is the same fixed 1.5V output LDO in an SOIC-8 package — same PSRR, same protection set, same 1.5A rating, but a different footprint. The adjustable-output sibling LT1963AES8#PBF (1.21V reference) can be set to 1.5V with a resistor divider, also in SOIC-8. Neither is a drop-in replacement for the D²Pak footprint; a board respin is required.
