Product details

Fixed 4.7V rail for noise-sensitive loads

Its 63 dB PSRR at 1 kHz makes it a candidate for powering analog front-end circuits, sensor bias rails, or low-noise op-amp supplies where a clean 4.7 V rail is needed and the load stays under 50 mA.

Dropout and quiescent budget

Maximum dropout is 0.22 V at the full 50 mA load, so the input rail can sit as low as 4.92 V and still maintain regulation.

Industrial temperature grade and protection

On-chip protection includes over-current, over-temperature, and short-circuit shutdown — no external watchdog needed for fault recovery.

Frequently asked questions

Is LP2980IM5X-4.7 obsolete?

Yes, Texas Instruments lists the LP2980IM5X-4.7 as obsolete. No official replacement part number has been published. For sustainment of existing designs, the independent surplus and broker channel is the sourcing route.

What is the maximum output current of LP2980IM5X-4.7?

Rated for 50 mA continuous output. Dropout at that load is 0.22 V maximum. For loads above 50 mA, a higher-current LDO in the same family would be needed.

Can LP2980IM5X-4.7 be used in the SOT-753 package?

Yes. The LP2980IM5X-4.7 is supplied in an SC-74A / SOT-753 package, which is functionally equivalent to the SOT-23-5 footprint. The tape-and-reel suffix (IM5X) indicates the reeled quantity for automated assembly.
