LP2966IMMX-2525 Equivalent & Substitute Parts Reference

Part Overview

The Texas Instruments LP2966IMMX-2525 is an obsolete Linear Voltage Regulator IC from the Power Management (PMIC) category. It features a positive fixed output configuration, dual regulators, 2.5V output voltage, and a maximum output current of 150mA in a surface-mount 8-VSSOP package. Due to its product status as obsolete, sourcing alternatives or substitutes with identical electrical and mechanical parameters is necessary for continued design support and maintenance.

Substitute Part Grouping Explanation

Substitute models for the LP2966IMMX-2525 are grouped using only allowed electrical and mechanical parameters. Selection considers:

• Output configuration (Positive)
• Output type (Fixed)
• Number of regulators (2)
• Maximum input voltage (7V)
• Fixed output voltage (2.5V)
• Maximum output current (150mA)
• Maximum dropout voltage at rated output current (0.27V @ 150mA)
• Quiescent and supply current
• PSRR
• Control and protection features
• Operating temperature range
• Surface-mount package compatibility (8-TSSOP, 8-MSOP, 8-VSSOP)
• RoHS and REACH compliance status

These criteria ensure the substitute part functions identically within applications originally designed for LP2966IMMX-2525.

Parameter Comparison

Engineering Selection Recommendations

Based on the product status and compliance data, LP2966IMMX-2525 is obsolete. LP2966IMM-2525/NOPB serves as a parametric equivalent with active product status and ROHS3/REACH compliance, making it suitable as a replacement. Moisture Sensitivity Level (MSL) is improved in the substitute, with unlimited floor life compared to the original's 168-hour limit.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the LP2966IMMX-2525?
Critical parameters include output voltage, output current, dropout voltage, regulator count, package type, control/protection features, and compliance certifications.

Q2: Does the substitute part LP2966IMM-2525/NOPB match the mechanical footprint of the original part?
Yes. Both parts use the 8-VSSOP package, supporting direct placement and assembly compatibility.

Q3: Is the protection feature set equivalent between the two parts?
Yes. Both offer over current, over temperature, and short circuit protection.

Q4: Are operating temperature ranges identical between main and substitute parts?
Yes. Both specify an operating temperature range of -40°C to 125°C.

Q5: Does the MSL difference affect board assembly?
LP2966IMM-2525/NOPB has a lower sensitivity (unlimited floor life); LP2966IMMX-2525 has a 168-hour limit. Both support standard surface-mount manufacturing processes.

Q6: Do both parts comply with ROHS and REACH?
Yes. Both are ROHS3 compliant and REACH unaffected.

Q7: Should additional qualification be done due to status change?
Selection decisions are based strictly on provided product status and compliance data. The substitute matches all allowed parameters for direct replacement.
