MIC2211-PSBML-TR Equivalent & Substitute Parts

Part Overview

The MIC2211-PSBML-TR is a linear voltage regulator IC from Microchip Technology designed for positive fixed output applications. This dual-output regulator delivers 150mA and 300mA at fixed 3V and 3.3V outputs, housed in a 10-MLF® (3x3) surface mount package. The device is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across output voltage, current delivery, dropout voltage, and thermal performance parameters while accommodating packaging variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC2211-PSBML-TR are qualified based on the following electrical and mechanical criteria:

Primary Equivalence Criteria:

• Dual positive fixed output configuration at 3V and 3.3V
• Output current capability of 150mA and 300mA
• Maximum input voltage of 5.5V or higher
• Dropout voltage performance within specified ranges
• Enable control feature
• Over current and over temperature protection
• Surface mount packaging in 10-pin form factor
• Operating temperature range of -40°C to 125°C or wider

Substitute Classification:

Parametric Equivalent: MIC2211-PSYML-TR (Microchip Technology) — Identical electrical specifications and output configuration. Differs only in product status (Active vs. Discontinued) and RoHS compliance level. Same 10-MLF® package footprint ensures direct PCB compatibility.

Manufacturer Recommended Equivalent: LP5996SD-3033/NOPB (Texas Instruments) — Meets all core electrical requirements with minor parameter variations. Different package designation (10-SON vs. 10-MLF®) requires PCB layout verification for pin compatibility and thermal performance. Input voltage maximum increased to 6V. Operating temperature range limited to -40°C ~ 85°C.

Parameter Comparison

Engineering Selection Recommendations

MIC2211-PSYML-TR is the primary substitute for direct replacement applications. This part maintains identical electrical specifications and package footprint compatibility with the MIC2211-PSBML-TR. The transition from discontinued to active product status ensures supply chain continuity. ROHS3 compliance provides regulatory advantage for new designs and manufacturing environments with RoHS requirements.

LP5996SD-3033/NOPB serves as an alternative substitute when supply constraints affect Microchip parts. This Texas Instruments device meets core functional requirements with the following considerations: the 10-SON package differs from the 10-MLF® package, requiring PCB layout verification for pin-to-pin compatibility and thermal pad alignment. The operating temperature maximum of 85°C is lower than the original part's 125°C rating, limiting use in high-temperature applications. Quiescent current is elevated at 110 µA versus 80 µA. ROHS3 compliance is maintained.

Selection between these substitutes depends on supply availability, thermal environment requirements, and PCB layout constraints. Both parts are ROHS3 compliant and carry active product status.

Frequently Asked Questions (FAQ)

Q: Can MIC2211-PSYML-TR replace MIC2211-PSBML-TR without PCB modifications?

A: Yes. The MIC2211-PSYML-TR is a parametric equivalent with identical electrical specifications and 10-MLF® package footprint. No PCB layout changes are required for direct substitution.

Q: What are the key differences between MIC2211-PSYML-TR and LP5996SD-3033/NOPB?

A: Both parts deliver the same output voltages and currents. The LP5996SD-3033/NOPB uses a 10-SON package instead of 10-MLF®, which may require PCB layout verification. The LP5996 has a lower operating temperature maximum (85°C vs. 125°C), higher quiescent current (110 µA vs. 80 µA), and slightly different dropout voltage characteristics at 300mA output (0.55V vs. 0.42V).

Q: Is the LP5996SD-3033/NOPB suitable for applications requiring -40°C to 125°C operation?

A: No. The LP5996SD-3033/NOPB is rated only to 85°C maximum operating temperature. Applications requiring the full -40°C to 125°C range must use MIC2211-PSYML-TR or equivalent Microchip parts.

Q: Are package footprints between 10-MLF® and 10-SON compatible?

A: Both are 10-pin surface mount packages in 3x3mm form factor with exposed thermal pads. Pin pitch and pad dimensions differ between MLF® and SON variants. PCB layout verification is required before substituting LP5996SD-3033/NOPB for MLF®-based designs.

Q: What is the impact of higher quiescent current in the LP5996SD-3033/NOPB?

A: The LP5996 draws 110 µA quiescent current versus 80 µA for the MIC2211 series. In battery-powered or low-power standby applications, this 30 µA difference may affect power budget calculations and standby current specifications.

Q: Are all substitute parts ROHS3 compliant?

A: MIC2211-PSYML-TR and LP5996SD-3033/NOPB are both ROHS3 compliant. The original MIC2211-PSBML-TR is RoHS non-compliant. Designs transitioning to compliant manufacturing environments should use either substitute part.
