Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC5219BMM is determined by strict equivalence across the following electrical and mechanical parameters:

• Output configuration (Positive Adjustable)
• Output current capability (500mA)
• Maximum input voltage (12V)
• Dropout voltage specification (0.6V @ 500mA)
• Quiescent current (8 µA)
• PSRR performance (75dB at 120Hz)
• Package type (8-MSOP)
• Operating temperature range (-40°C to 125°C)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Control features (Enable function)

The MIC5219YMM meets all these criteria and is classified as a direct substitute within the same product family.

Parameter Comparison

Engineering Selection Recommendations
