Substitute Part Grouping Explanation

Substitute parts for the LP2980AIM5-2.5 are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Texas Instruments LP2980 Series): LP2980AIM5-2.5/NOPB, LP2980AIM5X-2.5/NOPB, LP2980IM5-2.5/NOPB, and LP2980IM5X-2.5/NOPB maintain identical electrical specifications including 2.5V fixed output, 50mA output current, 0.22V dropout voltage, 95 µA quiescent current, and 63dB PSRR. These parts differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) and product status (Active, Last Time Buy, or Obsolete). All share the SOT-23-5 package footprint and identical protection features.

Manufacturer Recommended Substitute (Microchip Technology MIC5225-2.5YM5-TR): This part provides higher output current capability (150mA versus 50mA) while maintaining the same 2.5V fixed output voltage, 16V maximum input voltage, SOT-23-5 package, and operating temperature range. The MIC5225 features different protection characteristics (includes Reverse Polarity protection) and higher dropout voltage (0.45V @ 150mA). This substitute is suitable for applications requiring increased current capacity within the same voltage and package constraints.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete LP2980AIM5-2.5, select LP2980AIM5-2.5/NOPB or LP2980IM5X-2.5/NOPB. Both maintain identical electrical and thermal specifications with Active product status, ensuring long-term availability and supply chain continuity. LP2980AIM5-2.5/NOPB is available in Cut Tape and Digi-Reel packaging formats, while LP2980IM5X-2.5/NOPB is supplied in Tape & Reel format with the highest current inventory (3447 pcs).

For applications requiring increased output current capacity beyond 50mA, the MIC5225-2.5YM5-TR from Microchip Technology provides 150mA output current in the same SOT-23-5 package. This substitute maintains voltage regulation at 2.5V and the same operating temperature range, with ROHS3 compliance and MSL 1 rating. The higher dropout voltage (0.45V @ 150mA) must be evaluated against circuit design requirements.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, ensuring regulatory and environmental compliance equivalent to the original part.

Frequently Asked Questions (FAQ)

Q: Can LP2980AIM5-2.5/NOPB be used as a direct replacement for LP2980AIM5-2.5?

A: Yes. Both parts are electrically and mechanically identical. The primary difference is product status (Active versus Obsolete) and packaging format. LP2980AIM5-2.5/NOPB is the recommended replacement due to its Active status and continued availability.

Q: What is the difference between LP2980AIM5X-2.5/NOPB and LP2980IM5X-2.5/NOPB?

A: Both parts share identical electrical specifications, operating temperature range, and package type (SOT-23-5). The difference lies in the manufacturing process designation (AIM versus IM). Both are suitable direct replacements with Active product status.

Q: Can MIC5225-2.5YM5-TR replace LP2980AIM5-2.5 in all applications?

A: The MIC5225-2.5YM5-TR is electrically compatible for voltage regulation (2.5V output) and package footprint (SOT-23-5). However, it provides 150mA output current versus 50mA, and exhibits higher dropout voltage (0.45V @ 150mA versus 0.22V @ 50mA). Use this substitute only when the application can accommodate the higher dropout voltage or requires the increased current capacity.

Q: What packaging formats are available for LP2980 series substitutes?

A: LP2980AIM5-2.5/NOPB is available in Cut Tape (CT) and Digi-Reel formats. LP2980AIM5X-2.5/NOPB and LP2980IM5X-2.5/NOPB are supplied in Tape & Reel (TR) format. All maintain the same SOT-23-5 package footprint and pin configuration.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts, including LP2980AIM5-2.5/NOPB, LP2980AIM5X-2.5/NOPB, LP2980IM5-2.5/NOPB, LP2980IM5X-2.5/NOPB, and MIC5225-2.5YM5-TR, are ROHS3 compliant with MSL 1 rating and REACH Unaffected status.

Q: Which substitute offers the best long-term availability?

A: LP2980IM5X-2.5/NOPB has the highest current inventory (3447 pcs) with Active product status, providing optimal long-term supply chain security. LP2980AIM5-2.5/NOPB is also Active with 1709 pcs in stock.
