LP2966IMM-5050 Equivalent & Substitute Parts

Part Overview

The LP2966IMM-5050 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications. This dual-output regulator delivers 150mA per channel with integrated protection features including over-current, over-temperature, and short-circuit protection. The device operates across an industrial temperature range of -40°C to 125°C and is housed in an 8-VSSOP surface-mount package.

The LP2966IMM-5050 carries an obsolete product status. Identifying equivalent and substitute parts is essential for design continuity, procurement planning, and ensuring long-term supply chain reliability for applications currently utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP2966IMM-5050 is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Fixed)
• Number of regulators (2)
• Fixed output voltage (5V)
• Maximum input voltage (7V)
• Maximum dropout voltage (0.27V @ 150mA)
• Output current capability (150mA)
• Quiescent current (300 µA)
• PSRR performance (60dB ~ 40dB at 120Hz)
• Control features (Enable function)
• Protection features (Over Current, Over Temperature, Short Circuit)
• Operating temperature range (-40°C ~ 125°C)
• Surface-mount packaging in 8-VSSOP configuration

The LP2966IMM-5050/NOPB qualifies as a parametric equivalent substitute. This variant maintains identical electrical specifications and functional characteristics while differing only in packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The LP2966IMM-5050/NOPB is the direct parametric equivalent for the obsolete LP2966IMM-5050. Both devices are manufactured by Texas Instruments and share identical electrical and functional specifications across all critical parameters.

The primary distinction between these parts is product status and compliance posture. The LP2966IMM-5050 is obsolete and carries RoHS non-compliant status. The LP2966IMM-5050/NOPB maintains active product status and achieves ROHS3 compliance, making it the preferred selection for new designs and ongoing production requirements.

Both parts are supplied in 8-VSSOP surface-mount packaging. The LP2966IMM-5050/NOPB is available in Tape & Reel packaging format, which is standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can the LP2966IMM-5050/NOPB directly replace the LP2966IMM-5050 in existing designs?

A: Yes. The LP2966IMM-5050/NOPB is a parametric equivalent with identical electrical specifications, output voltage, current ratings, protection features, and operating temperature range. Both devices use the same 8-VSSOP package footprint and pinout.

Q: What is the difference between LP2966IMM-5050 and LP2966IMM-5050/NOPB?

A: The primary differences are packaging format (standard vs. Tape & Reel), product status (Obsolete vs. Active), and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical performance and functional characteristics are identical.

Q: Why is the LP2966IMM-5050 marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and product lifecycle decisions. The LP2966IMM-5050/NOPB remains in active production and serves as the current equivalent.

Q: Are there any compatibility concerns when switching from LP2966IMM-5050 to LP2966IMM-5050/NOPB?

A: No compatibility concerns exist. Both devices share identical pinout, package dimensions (8-VSSOP, 0.118" width, 3.00mm), and electrical specifications. PCB layout and circuit design require no modification.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" suffix indicates the part is supplied in Tape & Reel packaging without plating on the leads, which is standard for high-volume automated assembly operations.

Q: Is the LP2966IMM-5050/NOPB suitable for new product designs?

A: Yes. The LP2966IMM-5050/NOPB carries active product status and ROHS3 compliance, making it the appropriate choice for new designs requiring a dual-output 5V linear regulator with 150mA per channel capability.
