MIC2211-PWBML-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC2211-PWBML-TR is a dual µCap low dropout regulator in a 10-pin 3mm × 3mm MLF package. It provides two independent outputs: Output 1 delivers up to 150mA, and Output 2 delivers up to 300mA. The specific PWB suffix indicates fixed output voltages of 3.0V for Output 1 and 1.6V for Output 2. Operating from an input range of 2.25V to 5.5V, it features 1% initial accuracy, ultra-low quiescent current of 48µA total, and thermal/current limit protection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the exact part number MIC2211-PWBML-TR against official Microchip or Micrel documentation to confirm the 3.0V/1.6V voltage configuration associated with the 'PWB' suffix. Ensure the MLF package type matches design requirements. Confirm availability through authorized distributors as this component may be legacy. Cross-reference datasheet specifications for electrical limits before integration.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component for battery-powered applications requiring two distinct regulated rails with minimal footprint. The 3.0V/1.6V combination suits systems needing separate core and I/O power domains. Verify that the load currents do not exceed 150mA for the first regulator and 300mA for the second. Ensure input voltage remains within the 2.25V to 5.5V range for proper regulation and dropout performance.
