LP8900TLX-AAEC/NOPB Equivalent & Substitute Parts

Part Overview

The LP8900TLX-AAEC/NOPB is a linear voltage regulator IC from Texas Instruments designed for power management applications. This dual-output positive fixed regulator delivers 200mA per output at 2.7V with a maximum dropout voltage of 0.16V at full load. The device is housed in a 6-DSBGA package measuring 1.5x1.3mm and operates across the industrial temperature range of -40°C to 85°C.

The LP8900TLX-AAEC/NOPB is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP8900TLX-AAEC/NOPB are identified based on the following critical parameters that define functional equivalence:

• Dual-output configuration (2 regulators)
• Fixed positive output voltage of 2.7V
• Output current capability of 200mA or greater per channel
• Maximum input voltage of 5.5V or higher
• Dropout voltage performance suitable for 200mA operation
• Surface mount packaging in compact form factors
• Operating temperature range of -40°C to 85°C
• Enable control feature
• Over temperature and short circuit protection

Two substitute parts meet these criteria with varying degrees of parametric alignment and product status considerations.

Engineering Selection Recommendations

LP8900TLE-AAAH/NOPB (Parametric Equivalent)

The LP8900TLE-AAAH/NOPB is the direct parametric equivalent to the LP8900TLX-AAEC/NOPB. Both devices are manufactured by Texas Instruments and share identical electrical specifications, including 200mA output current, 0.16V dropout voltage at full load, and 2.7V fixed output voltage. The primary difference is product status: LP8900TLE-AAAH/NOPB is active with 1863 units in stock, while the original part is obsolete. Both are ROHS3 compliant and carry MSL 1 rating. The packaging is identical (6-DSBGA, 1.5x1.3mm). This part is the preferred direct replacement for the LP8900TLX-AAEC/NOPB.

ISL9016IRUGGZ-T (Manufacturer Recommended Alternative)

The ISL9016IRUGGZ-T from Renesas Electronics Corporation is an active alternative that maintains dual-output configuration and 2.7V fixed output voltage. This device offers enhanced protection features including over current, soft start, and under voltage lockout (UVLO) in addition to over temperature protection. The ISL9016IRUGGZ-T operates with a higher maximum input voltage of 6.5V compared to 5.5V for the original part. However, the output current per channel is reduced to 150mA versus 200mA, and dropout voltage increases to 0.325V at 150mA. The package changes from 6-DSBGA to 6-UTDFN (1.6x1.6mm), requiring PCB layout modification. Quiescent current is lower at 67 µA. This part is suitable for applications where the reduced current capability and package change are acceptable, and where the enhanced protection features provide system-level benefits.

Frequently Asked Questions (FAQ)

Q: Can LP8900TLE-AAAH/NOPB be used as a direct drop-in replacement for LP8900TLX-AAEC/NOPB?

A: Yes. The LP8900TLE-AAAH/NOPB is parametrically identical to the LP8900TLX-AAEC/NOPB. Both devices share the same electrical specifications, output current rating of 200mA, dropout voltage of 0.16V at full load, and identical 6-DSBGA packaging. No circuit modifications or PCB layout changes are required.

Q: What are the key differences between LP8900TLE-AAAH/NOPB and ISL9016IRUGGZ-T?

A: The primary differences are output current capability and package form factor. LP8900TLE-AAAH/NOPB delivers 200mA per output in a 6-DSBGA package, while ISL9016IRUGGZ-T delivers 150mA per output in a 6-UTDFN package. Dropout voltage differs significantly: 0.16V versus 0.325V at rated current. ISL9016IRUGGZ-T includes additional protection features (over current, soft start, UVLO) and operates with a higher maximum input voltage of 6.5V. The ISL9016IRUGGZ-T requires PCB layout modification due to package change.

Q: Is the ISL9016IRUGGZ-T suitable for applications requiring 200mA output current?

A: No. The ISL9016IRUGGZ-T is rated for 150mA per output channel, which is 25% lower than the original LP8900TLX-AAEC/NOPB specification of 200mA. Applications requiring the full 200mA output current must use LP8900TLE-AAAH/NOPB.

Q: What packaging considerations apply when selecting a substitute?

A: LP8900TLE-AAAH/NOPB uses the same 6-DSBGA (1.5x1.3mm) package as the original part, requiring no PCB modifications. ISL9016IRUGGZ-T uses a 6-UTDFN (1.6x1.6mm) package with exposed pad, necessitating PCB layout redesign, thermal management evaluation, and re-qualification of the assembly process.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both LP8900TLE-AAAH/NOPB and ISL9016IRUGGZ-T are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of the original LP8900TLX-AAEC/NOPB.

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

A: For applications matching the original electrical specifications (200mA output current, 0.16V dropout voltage, 5.5V maximum input), LP8900TLE-AAAH/NOPB is the recommended choice due to parametric equivalence and identical packaging. ISL9016IRUGGZ-T is suitable only when the reduced current capability (150mA), higher dropout voltage (0.325V), and enhanced protection features align with system requirements, and when PCB layout modification is feasible.
