LP3985ITL-3.0/NOPB Equivalent & Substitute Parts

Part Overview

The LP3985ITL-3.0/NOPB is a linear voltage regulator IC from Texas Instruments designed for power management applications. This positive fixed output regulator delivers 150mA at 3V output with a maximum dropout voltage of 0.1V at rated current. The device is housed in a 5-DSBGA package and includes integrated protection features for over-current, over-temperature, and short-circuit conditions. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when parametric specifications, electrical performance, and package compatibility align with the original design requirements.

Substitute Part Grouping Explanation

Substitute parts for the LP3985ITL-3.0/NOPB are identified based on strict parametric equivalence. The substitution criteria include identical output voltage (3V), matching output current capability (150mA), equivalent dropout voltage performance (0.1V @ 150mA), identical package type (5-DSBGA), matching control features (Enable), and equivalent protection mechanisms (Over Current, Over Temperature, Short Circuit). The substitute must maintain the same operating temperature range (-40°C ~ 125°C), PSRR characteristics (50dB ~ 40dB at 1kHz ~ 10kHz), and regulatory compliance status (ROHS3 Compliant). Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility and represent distribution channel variations only.

Parameter Comparison

Engineering Selection Recommendations

Both LP3985ITL-3.0/NOPB and LP3985ITLX-3.0/NOPB are Active status products from Texas Instruments with identical electrical specifications and package geometry. Selection between these parts is determined by packaging format availability and supply chain requirements. The LP3985ITL-3.0/NOPB is supplied in Tape & Reel format, while the LP3985ITLX-3.0/NOPB is available in Cut Tape and Digi-Reel formats. Both parts maintain ROHS3 compliance and REACH unaffected status. The choice between these equivalents depends on procurement volume, assembly equipment compatibility, and inventory management practices rather than electrical performance or functional capability.

Frequently Asked Questions (FAQ)

Q: Are LP3985ITL-3.0/NOPB and LP3985ITLX-3.0/NOPB electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 3V fixed output, 150mA current capability, 0.1V maximum dropout voltage, and equivalent protection features across the full -40°C to 125°C operating range.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. LP3985ITL-3.0/NOPB uses Tape & Reel distribution, while LP3985ITLX-3.0/NOPB uses Cut Tape and Digi-Reel formats. The physical package (5-DSBGA) and all electrical characteristics remain identical.

Q: Can I substitute LP3985ITLX-3.0/NOPB for LP3985ITL-3.0/NOPB on a PCB assembly?

A: Yes. The 5-DSBGA package dimensions (1.41x1.08) are identical for both parts. PCB footprints, solder reflow profiles, and assembly processes are compatible without modification.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should I select for high-volume production?

A: Selection depends on your assembly equipment and supply chain. Tape & Reel format (LP3985ITL-3.0/NOPB) suits automated pick-and-place systems, while Cut Tape format (LP3985ITLX-3.0/NOPB) accommodates manual assembly or specific feeder configurations. Electrical performance is identical for both.
