MIC5330-MMYML-TR

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

The MIC5330-MMYML-TR is a dual ultra-low dropout linear regulator from Microchip Technology, integrating two independent 300mA LDOs into an 8-pin 2mm x 2mm MLF package. It operates with an input voltage range of 2.3V to 5.5V and provides fixed output voltages of 2.8V for both channels. The device features ±2% initial output accuracy, ultra-low output noise of 30µVRMS, and high power supply rejection exceeding 70dB at 1kHz. It includes thermal shutdown and current limit protection, with a junction temperature range of -40°C to +125°C.

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

Verify the specific suffix 'MMYML' corresponds to the required 2.8V/2.8V fixed output configuration before procurement. Confirm that the MLF package type matches the PCB footprint requirements. Ensure the ordering part number aligns with the manufacturer's official documentation to avoid functional mismatches.

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

Select this component when dual isolated rails are needed within strict board space constraints. The µCap design allows stability with small ceramic capacitors, reducing overall system cost. Verify that the 90°C/W thermal resistance accommodates the expected ambient temperatures and load currents without triggering thermal shutdown.

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

How does the bypass pin affect performance?

Connecting a capacitor to the BYP pin reduces output voltage noise and improves power supply rejection ratio.

What happens if an enable pin is left floating?

Leaving an enable pin floating may cause an indeterminate state on the output; it must be driven high or low.
