MAX604CSA Linear Voltage Regulator IC

Part Overview

The MAX604CSA is a linear voltage regulator IC from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. This device functions as a positive adjustable (fixed) output regulator capable of delivering 500mA output current in a compact 8-SOIC surface mount package. The MAX604CSA is currently listed as obsolete, making identification of suitable substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX604CSA is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable/Fixed)
• Number of regulators (1)
• Maximum input voltage (11.5V)
• Output voltage range (1.25V to 11V)
• Maximum output current (500mA)
• Dropout voltage specification (0.82V @ 400mA)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Operating temperature range (0°C ~ 70°C)
• Package type (8-SOIC)
• Mounting type (Surface Mount)

The MAX604CSA+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction lies in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MAX604CSA+ serves as the direct functional equivalent to the MAX604CSA. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and equivalent circuit performance within the specified operating parameters.

The MAX604CSA+ is preferred for new designs and ongoing production due to its active product status and ROHS3 compliance. The MAX604CSA, being obsolete and RoHS non-compliant, is suitable only for legacy system maintenance where existing inventory is available and regulatory compliance is not a requirement.

Selection between these parts should be based on regulatory requirements, supply chain availability, and production timeline constraints. Both parts are functionally interchangeable within applications requiring positive adjustable/fixed output regulation at 500mA with the specified input and output voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can the MAX604CSA+ be used as a direct replacement for the MAX604CSA?
