Product details

50 mA LDO with 63 dB PSRR — the noise-sensitive rail choice

The LP2980AIM5-2.8/NOPB: 63 dB PSRR at 1 kHz suits analog front-ends and RF bias circuits. Maximum dropout is 0.22 V at 50 mA.

Industrial temperature grade and protection set

On-chip protection includes over-current, over-temperature, and short-circuit shutdown — no external watchdog or crowbar needed for fault survival. The enable pin gates the output rail during sleep.

Available stock is limited to surplus and excess inventory held by independent distributors. No official replacement or cross-reference is recorded in the TI lifecycle notice for this specific fixed-voltage variant. Buyers should evaluate the LP2980 family for a pin-compatible voltage option or consider a newer-generation LDO with equivalent SOT-23-5 footprint.

Package and footprint — SOT-23-5

Supplied in a 5-pin SOT-23-5 surface-mount package.

Frequently asked questions

Is LP2980AIM5-2.8/NOPB obsolete?

Yes, Texas Instruments lists this part as Obsolete. No factory orders are being accepted.

What is the replacement for LP2980AIM5-2.8/NOPB?

No official replacement has been published by Texas Instruments for this specific fixed 2.8 V output variant. The LP2980 family shares the same SOT-23-5 footprint and pinout across output voltages, so a different fixed-voltage LP2980 variant (e.g. 3.3 V or adjustable) may be a drop-in substitute if the output voltage can be changed. For a newer-generation LDO, evaluate parts with equivalent 50 mA rating and SOT-23-5 package.

What is the difference between LP2980AIM5-2.8/NOPB and LP2980AIM5-3.3?

The two parts are identical in package (SOT-23-5), pinout, 50 mA output current, dropout voltage, and protection features. The only difference is the fixed output voltage: 2.8 V for this part versus 3.3 V for the LP2980AIM5-3.3 variant. If your load can tolerate the voltage change, the 3.3 V version is a direct footprint and pin-compatible alternative.
