Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2980IM5-ADJ is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Output configuration (Positive), output type (Adjustable), number of regulators (1), input voltage maximum (16V), output voltage range (1.23V to 15V), dropout voltage (0.22V @ 50mA), output current (50mA), quiescent current (95 µA), PSRR (63dB @ 1kHz), control features (Enable), and protection features (Over Current, Over Temperature, Short Circuit).

Environmental & Compliance Parameters: Operating temperature range (-40°C ~ 125°C), RoHS3 compliance, MSL rating (1), and REACH status (Unaffected).

Physical Parameters: Surface Mount mounting type, SOT-23-5 package configuration (SC-74A, SOT-753 case).

All substitute parts listed maintain identical electrical performance, thermal characteristics, and regulatory compliance with the main part number.

Parameter Comparison

Engineering Selection Recommendations

The LP2980IM5-ADJ is designated Last Time Buy status. For new designs and ongoing procurement, LP2980IM5-ADJ/NOPB is the direct manufacturer equivalent with Active product status. This part maintains identical electrical specifications, thermal performance, and regulatory compliance while offering standard long-term availability.

LP2980IM5X-ADJ/NOPB is a parametric equivalent with Active product status. This variant provides the same functional performance and electrical characteristics as the main part number across all critical parameters. Both substitute parts carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original design.

Selection between LP2980IM5-ADJ/NOPB and LP2980IM5X-ADJ/NOPB depends on procurement availability and supply chain requirements, as both deliver identical performance in the SOT-23-5 package configuration.

Frequently Asked Questions (FAQ)

Q: Can LP2980IM5-ADJ/NOPB be used as a direct replacement for LP2980IM5-ADJ?

A: Yes. LP2980IM5-ADJ/NOPB is a direct manufacturer equivalent with identical electrical specifications, output voltage range (1.23V to 15V), 50mA output current, and SOT-23-5 package configuration. The primary difference is product status: LP2980IM5-ADJ/NOPB is Active, while the original is Last Time Buy.

Q: What is the difference between LP2980IM5-ADJ/NOPB and LP2980IM5X-ADJ/NOPB?

A: Both parts are parametric equivalents with identical electrical performance. They deliver the same output voltage range, current capacity, dropout voltage, and protection features. Both are Active status parts in SOT-23-5 packaging. The designation difference reflects manufacturing or qualification variants from Texas Instruments.

Q: Are all three part numbers compatible with the same PCB layout?

A: Yes. All three part numbers use the SOT-23-5 package (SC-74A, SOT-753 case), ensuring identical pin configuration and PCB footprint compatibility. No layout modifications are required when substituting between these parts.

Q: Do the substitute parts maintain the same thermal and compliance characteristics?

A: Yes. LP2980IM5-ADJ/NOPB and LP2980IM5X-ADJ/NOPB maintain identical operating temperature range (-40°C ~ 125°C), ROHS3 compliance, MSL rating (1), and REACH Unaffected status. Thermal performance and regulatory requirements are equivalent across all three part numbers.

Q: Which substitute part should be selected for new designs?

A: For new designs, either LP2980IM5-ADJ/NOPB or LP2980IM5X-ADJ/NOPB is appropriate, as both are Active status parts with identical specifications. Selection should be based on current supply chain availability and procurement lead times.
