Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP3985IBL-5.0 are identified based on parametric equivalence within the LP3985 product family. The substitution criteria are strictly defined by the following key parameters:

• Output voltage: 5V fixed
• Output current capability: 150mA
• Maximum input voltage: 6V
• Voltage dropout: 0.1V @ 150mA
• Package type: 5-DSBGA (1.41x1.08)
• Protection features: Over Current, Over Temperature, Short Circuit
• Control features: Enable function
• Operating temperature range: -40°C ~ 125°C
• RoHS3 compliance and MSL Level 1

The LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB variants meet all these criteria and are classified as active products, making them suitable replacements for the obsolete LP3985IBL-5.0.

Parameter Comparison

Engineering Selection Recommendations

Both LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB are direct parametric equivalents to the LP3985IBL-5.0. The primary distinction between these substitutes is product status and packaging format:

LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB are classified as active products with current manufacturing availability, whereas the LP3985IBL-5.0 is obsolete. Both substitute parts maintain identical electrical specifications, thermal performance, and protection characteristics. All three variants comply with ROHS3 requirements and REACH regulations, ensuring regulatory compliance across applications.

For new designs or production requiring the LP3985 5V/150mA regulator, selection between the active substitutes should be based on packaging format requirements and supplier inventory availability.

Frequently Asked Questions (FAQ)

Q: Can LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB be used interchangeably with LP3985IBL-5.0?

A: Yes. All three parts share identical electrical specifications, output voltage, current rating, dropout voltage, protection features, and package dimensions (5-DSBGA 1.41x1.08). The primary difference is product status: the LP3985IBL-5.0 is obsolete, while the substitutes are active products.

Q: What is the difference between LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB?

A: Both parts are parametric equivalents with identical electrical and thermal characteristics. The difference lies in packaging format: LP3985ITL-5.0/NOPB is supplied in Tape & Reel format. Selection between them should be based on your procurement and assembly requirements.

Q: Are these substitutes compatible with existing PCB designs for LP3985IBL-5.0?

A: Yes. The substitute parts use the same 5-DSBGA package with identical pin configuration and dimensions (1.41x1.08mm). No PCB layout modifications are required.

Q: Do the substitute parts maintain the same protection features?

A: Yes. LP3985ITL-5.0/NOPB and LP3985ITLX-5.0/NOPB include identical protection: over-current, over-temperature, and short-circuit protection, matching the LP3985IBL-5.0 specification.

Q: Are there any compliance or regulatory differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity). Regulatory compliance is maintained across all variants.
