MIC5339-MGYMT-TR

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

The MIC5339-MGYMT-TR is a dual 300mA low dropout regulator featuring fixed outputs of 2.8V and 1.8V. It operates within an input voltage range of 2.5V to 5.5V, delivering high output accuracy of ±2%. The device maintains a total quiescent current of 70µA with both outputs enabled and achieves a low dropout voltage of 220mV at full load. It incorporates independent enable pins, thermal shutdown, current limit protection, and an active auto-discharge circuit for rapid output discharge upon disabling.

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

Verify the specific ordering suffix against official Microchip documentation to confirm the exact output voltage configuration and package variant. Ensure compatibility with RoHS compliance standards and lead-free requirements specified for the Thin MLF® package. Confirm availability status through authorized distributors as supply levels may fluctuate.

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

Select this component for portable applications requiring two distinct regulated voltages from a single small footprint. The 2.8V/1.8V output combination suits systems needing separate logic and analog power rails. Verify that the required output capacitance meets stability criteria for ceramic capacitors and that the thermal dissipation remains within junction temperature limits under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The MIC5339 belongs to the MIC5338/9 family of advanced dual low dropout regulators designed for general-purpose portable devices. It shares architectural similarities with the MIC5338 but distinguishes itself by including an active discharge feature on its outputs. This family targets applications demanding low noise, excellent PSRR, and minimal board space utilization.
