MIC2211-SMYML

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

The MIC2211-SMYML is a dual-output, fixed positive Low Dropout (LDO) regulator manufactured by Microchip Technology. It features two independent linear regulators housed in a compact 10-lead MLF package measuring 3mm x 3mm. The first output provides a fixed voltage of 1.8V with a maximum current capability of 150mA. The second output delivers a fixed voltage of 2.8V with a maximum current capability of 300mA. The device operates from an input voltage range up to 5.5V and includes enable pins for individual control of each output channel.

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

Verify the specific suffix against official Microchip documentation to confirm exact output voltages and current ratings, as variations exist within the MIC2211 family. Ensure the component source is authorized to guarantee authenticity and compliance with RoHS standards. Check datasheet revisions for any packaging or manufacturing site changes that may affect compatibility.

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

Select this component when board space is limited due to its small 3mm x 3mm MLF footprint. It is appropriate for designs requiring two distinct fixed voltage rails from a single input source. Consider the low dropout characteristics and high PSRR if powering sensitive analog or RF sections. Verify that the required load currents do not exceed the 150mA and 300mA limits for the respective outputs.

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

The MIC2211 series belongs to Microchip's portfolio of µCap LDO regulators, originally developed by Micrel before acquisition. These devices are designed to operate stably with very small ceramic output capacitors, reducing overall system cost and board area compared to traditional LDOs requiring larger tantalum or electrolytic capacitors.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Cross-reference with other MIC2211 variants such as MIC2211-GMYML-TR or MIC2211-MSYML-TR to find alternatives with different fixed output voltage combinations. Ensure the replacement part maintains the same 10-MLF package dimensions and pinout configuration for direct board compatibility.
