MIC29152BU Equivalent & Substitute Parts

Part Overview

The MIC29152BU is a linear voltage regulator IC from Microchip Technology designed for positive adjustable output applications. It delivers 1.5A output current with an adjustable voltage range from 1.25V to 25V, housed in a TO-263-5 surface mount package. The device includes integrated protection features for over-current, over-temperature, reverse polarity, and transient voltage conditions.

The MIC29152BU is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC29152BU is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Maximum input voltage (26V)
• Output voltage range (1.25V to 25V)
• Maximum output current (1.5A)
• Dropout voltage specification (0.6V @ 1.5A)
• Control features (Enable)
• Protection features (Over Current, Over Temperature, Reverse Polarity, Transient Voltage)
• Operating temperature range (-40°C ~ 125°C)
• Mounting type (Surface Mount)
• Package type (TO-263-5)

The MIC29152WU meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MIC29152WU is the direct substitute for the MIC29152BU. Both parts share identical electrical and mechanical specifications across all functional parameters. The MIC29152WU is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance certification. The MIC29152BU, being obsolete and RoHS non-compliant, should be transitioned to the MIC29152WU to ensure long-term supply chain viability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MIC29152WU replace MIC29152BU in existing designs?

A: Yes. The MIC29152WU is electrically and mechanically equivalent to the MIC29152BU. All functional parameters, including output voltage range, current rating, dropout voltage, protection features, and package type, are identical. Direct substitution is possible without circuit modification.

Q: What is the primary difference between these parts?

A: The MIC29152BU is obsolete, while the MIC29152WU is active. Additionally, the MIC29152WU is ROHS3 compliant, whereas the MIC29152BU is RoHS non-compliant. The MIC29152WU is supplied in tube packaging.

Q: Are there any package compatibility concerns?

A: No. Both parts use the TO-263-5 package (D2PAK with 5 leads plus tab). Pin configuration and footprint are identical, enabling direct PCB-level substitution.

Q: Does the MIC29152WU maintain the same protection features?

A: Yes. Both parts include identical protection features: over-current, over-temperature, reverse polarity, and transient voltage protection. Functional safety characteristics are preserved.

Q: What is the operating temperature range for both parts?

A: Both the MIC29152BU and MIC29152WU operate across -40°C to 125°C, ensuring compatibility across the full specified temperature range.
