AP7175SP-13 Equivalent & Substitute Parts

Part Overview

The AP7175SP-13 is a linear voltage regulator IC from Diodes Incorporated designed for positive adjustable output applications. This device delivers 3A output current with adjustable voltage regulation from 0.8V to 3.23V, featuring integrated protection mechanisms including over-current, over-temperature, power-on reset, and soft-start functionality. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The AP7175SP-13 operates across the industrial temperature range of -40°C to 85°C and is housed in an 8-SOIC package with exposed pad for enhanced thermal performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP7175SP-13 is determined by the following critical parameters:

• Output current capability: 3A minimum
• Output configuration: Positive adjustable topology
• Package type: 8-SOIC with exposed pad (thermal compatibility)
• Voltage output range: Minimum 0.8V lower bound, maximum output ≥3.2V
• Voltage input maximum: ≥3.65V
• Control features: Enable and Power Good functionality
• Protection features: Over-current and over-temperature protection as minimum requirements
• Operating temperature range: Support for -40°C to 85°C minimum
• Regulatory compliance: ROHS3 compliance required

The identified substitute parts meet these criteria while offering active product status and improved availability compared to the obsolete AP7175SP-13.

Parameter Comparison

Engineering Selection Recommendations

AP7176BSP-13 is the primary substitute for the AP7175SP-13. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications for output current, input voltage maximum, quiescent current, and control/protection features. The AP7176BSP-13 is in active product status with improved availability. The maximum output voltage specification is slightly lower (3.12V vs. 3.23V), and dropout voltage is marginally higher (0.53V vs. 0.42V @ 3A). Both devices maintain ROHS3 compliance and MSL-1 rating. The 8-SOIC package with exposed pad is identical, ensuring direct mechanical compatibility.

MIC59300YME-TR from Microchip Technology is an alternative substitute meeting the 3A output current and positive adjustable topology requirements. This device offers a higher maximum input voltage (3.8V), lower minimum output voltage (0.5V), and superior dropout voltage performance (0.4V @ 3A). The MIC59300YME-TR extends the operating temperature range to 125°C and maintains ROHS3 compliance. However, it lacks the Power Good output feature present in the AP7175SP-13 and features a higher MSL rating (3 vs. 1). The 8-SOIC package with exposed pad maintains mechanical compatibility.

Selection between substitutes depends on specific application requirements: AP7176BSP-13 for closest electrical and feature parity with the obsolete part, or MIC59300YME-TR for applications requiring extended temperature operation and improved dropout voltage performance.

Frequently Asked Questions (FAQ)

Q: Can the AP7176BSP-13 directly replace the AP7175SP-13 in existing designs?

A: The AP7176BSP-13 is functionally compatible as a direct substitute. Both devices share the same 8-SOIC package with exposed pad, identical output current rating (3A), and matching control/protection feature sets. The primary differences are marginal: maximum output voltage is 0.11V lower (3.12V vs. 3.23V) and dropout voltage is 0.11V higher (0.53V vs. 0.42V @ 3A). Verify these specifications against your specific application voltage requirements before implementation.

Q: What are the key differences between the Diodes and Microchip substitutes?

A: The AP7176BSP-13 maintains closer electrical parity to the original AP7175SP-13, including identical quiescent current (1.5 mA) and matching control features (Enable and Power Good). The MIC59300YME-TR offers superior dropout voltage (0.4V) and extended temperature operation (-40°C to 125°C), but lacks the Power Good output and has a higher moisture sensitivity level (MSL-3 vs. MSL-1). Both meet the 3A output current and positive adjustable topology requirements.

Q: Are there package compatibility concerns when substituting these parts?

A: All three devices use the 8-SOIC (0.154", 3.90mm Width) package with exposed pad. The package footprint and pin configuration are identical, ensuring direct mechanical and thermal compatibility on existing PCB layouts. No package-related design modifications are required.

Q: Which substitute is recommended for new designs?

A: Selection depends on application-specific requirements. For designs requiring the Power Good output feature and closest electrical match to the original specification, use AP7176BSP-13. For applications prioritizing dropout voltage performance and extended temperature operation, use MIC59300YME-TR. Both devices are in active product status with established supply chains.

Q: What compliance certifications apply to these substitutes?

A: All three devices (AP7175SP-13, AP7176BSP-13, and MIC59300YME-TR) are ROHS3 compliant and REACH unaffected. The AP7176BSP-13 maintains MSL-1 rating (unlimited moisture sensitivity), while the MIC59300YME-TR carries MSL-3 rating (168-hour floor life). Both substitutes meet the same regulatory and environmental compliance standards as the original part.
