LP38502ASDX-ADJ/NOPB Equivalent & Substitute Parts

Part Overview

The LP38502ASDX-ADJ/NOPB is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. This Surface Mount device delivers 1.5A output current in an 8-WSON (3x2.5) package and operates across -40°C to 125°C. The part is Active status and ROHS3 compliant, making it suitable for production applications requiring adjustable positive voltage regulation with integrated protection features.

Substitute parts are identified when electrical performance parameters, mechanical compatibility, and regulatory compliance align with the main part specifications, enabling direct replacement in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the LP38502ASDX-ADJ/NOPB are classified into two categories based on substitution criteria:

Parametric Equivalents (Texas Instruments LP38502 Series): LP38502ASD-ADJ/NOPB, LP38502SD-ADJ/NOPB, and LP38502SDE-ADJ/NOPB are parametric equivalents sharing identical electrical specifications with the main part. These variants differ only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and inventory availability. All three maintain the same voltage ratings (5.5V input max, 0.6V to 5V output range), 1.5A output current, 0.37V dropout specification, and operating temperature range (-40°C to 125°C). Package configuration remains 8-WFDFN Exposed Pad across all variants.

Manufacturer Recommended Equivalent (Diodes Incorporated AP7362-HA-7): The AP7362-HA-7 is a cross-manufacturer substitute meeting core electrical requirements: positive adjustable output, 1.5A current capacity, 5.5V maximum input, 0.6V to 5V output range, and Surface Mount 8-pin DFN package. This part qualifies as a functional substitute based on matching output configuration, current rating, and voltage specifications. Differences exist in dropout voltage (0.24V versus 0.37V), quiescent current (1.2 mA versus 15 µA), and maximum operating temperature (85°C versus 125°C).

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments LP38502 Series Variants (LP38502ASD-ADJ/NOPB, LP38502SD-ADJ/NOPB, LP38502SDE-ADJ/NOPB): These parts are direct parametric equivalents with identical electrical and thermal specifications. Selection among these variants depends on packaging format requirements and supply chain availability. All three maintain Active product status and ROHS3 compliance. The choice between Cut Tape & Digi-Reel® and Tape & Reel packaging is determined by assembly process requirements and volume needs.

Diodes Incorporated AP7362-HA-7: This part qualifies as a functional substitute for applications where the operating temperature range does not exceed 85°C and where improved dropout voltage performance (0.24V versus 0.37V) provides design benefits. The AP7362-HA-7 maintains ROHS3 compliance and Active product status. Applications requiring the full -40°C to 125°C temperature range of the LP38502ASDX-ADJ/NOPB should not use this substitute. The higher quiescent current (1.2 mA versus 15 µA) may impact power consumption in low-power standby applications.

Frequently Asked Questions (FAQ)

Q: Can LP38502ASD-ADJ/NOPB, LP38502SD-ADJ/NOPB, and LP38502SDE-ADJ/NOPB be used interchangeably with LP38502ASDX-ADJ/NOPB? A: Yes. These parts share identical electrical specifications, voltage ratings, current capacity, and thermal performance. Differences exist only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). PCB layout and assembly compatibility remain unchanged.

Q: Is the AP7362-HA-7 a direct replacement for LP38502ASDX-ADJ/NOPB? A: The AP7362-HA-7 is a functional substitute for applications operating within -40°C to 85°C. It matches core electrical parameters: positive adjustable output, 1.5A current, 5.5V input maximum, and 0.6V to 5V output range. Applications requiring operation above 85°C must use the LP38502 series. The improved dropout voltage (0.24V) may reduce thermal dissipation in some designs.

Q: What are the package differences between these substitutes? A: LP38502ASDX-ADJ/NOPB, LP38502ASD-ADJ/NOPB, LP38502SD-ADJ/NOPB, and LP38502SDE-ADJ/NOPB all use 8-WFDFN Exposed Pad packaging. The AP7362-HA-7 uses 8-UFDFN Exposed Pad packaging. Both are 8-pin DFN packages with exposed thermal pads; PCB footprint compatibility requires verification against specific package dimensions.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitutes—LP38502ASD-ADJ/NOPB, LP38502SD-ADJ/NOPB, LP38502SDE-ADJ/NOPB, and AP7362-HA-7—are ROHS3 compliant with MSL rating 1 (Unlimited).

Q: What is the difference in quiescent current between LP38502 and AP7362-HA-7? A: LP38502 series devices draw 15 µA quiescent current. The AP7362-HA-7 draws 1.2 mA. In applications with extended low-power standby periods, this difference may impact overall system power consumption.
