LP3893ES-1.5/NOPB Equivalent & Substitute Parts

Part Overview

The LP3893ES-1.5/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive fixed 1.5V output at 3A capacity in a TO-263 (DDPAK-5) surface mount package. This device is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The part provides regulated output with integrated protection features including over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO) protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP3893ES-1.5/NOPB is determined by the following critical parameters:

• Fixed output voltage of 1.5V
• Minimum output current rating of 3A
• Maximum input voltage of 5.5V or greater
• TO-263 (DDPAK-5) package compatibility
• Surface mount configuration
• Operating temperature range of -40°C to 125°C or wider
• RoHS3 compliance

The LP3883ES-1.5/NOPB meets all substitution criteria as an active product from the same manufacturer with identical electrical specifications and package configuration.

Frequently Asked Questions (FAQ)

Q: Can the LP3883ES-1.5/NOPB directly replace the LP3893ES-1.5/NOPB in existing designs?

A: Yes. Both devices share identical output voltage (1.5V), output current (3A), input voltage specifications (5.5V max), package configuration (TO-263 DDPAK-5), and operating temperature range (-40°C to 125°C). Pin-for-pin compatibility and electrical equivalence are confirmed.

Q: What is the primary difference between these two parts?

A: The LP3893ES-1.5/NOPB is obsolete, while the LP3883ES-1.5/NOPB is an active product. The LP3883ES-1.5/NOPB also demonstrates improved voltage dropout performance (0.42V @ 3A versus 1V @ 1A).

Q: Are there any package or mounting differences?

A: No. Both parts use the TO-263 (DDPAK-5) surface mount package with identical mechanical and thermal characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LP3893ES-1.5/NOPB and LP3883ES-1.5/NOPB are ROHS3 compliant with MSL rating 3 (168 Hours), REACH unaffected status, and EAR99 ECCN classification.

Q: Is there a performance advantage to using the LP3883ES-1.5/NOPB?

A: The LP3883ES-1.5/NOPB exhibits lower voltage dropout at full load (0.42V @ 3A), which may reduce thermal dissipation in applications operating near the minimum input voltage threshold.
