MIC5259-2.85BML-TR Equivalent & Substitute Parts

Part Overview

The MIC5259-2.85BML-TR is a linear voltage regulator IC from Microchip Technology designed for positive fixed output applications. This device delivers 300mA output current at a fixed 2.85V output voltage with a maximum dropout voltage of 0.55V at full load. The regulator integrates protection features including over-current, over-temperature, and under-voltage lockout (UVLO) functionality, making it suitable for low-power supply applications requiring stable voltage regulation.

The MIC5259-2.85BML-TR is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. Direct substitutes maintain identical electrical specifications and package configurations while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution eligibility for the MIC5259-2.85BML-TR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.85V
• Output current rating of 300mA
• Maximum input voltage of 6V
• Dropout voltage specification of 0.55V @ 300mA
• Quiescent current of 150 µA
• PSRR performance of 65dB ~ 53dB (10Hz ~ 10kHz)
• Operating temperature range of -40°C ~ 125°C
• Package configuration: 6-DFN (2x2) with exposed pad
• Identical protection and control feature set

The MIC5259-2.85YML-TR meets all substitution criteria as a direct equivalent from the same manufacturer, maintaining 100% electrical and mechanical compatibility while offering improved product status and regulatory compliance.

Parameter Comparison
