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

Verify that the specific suffix SGYMT corresponds to the required 3.3V/1.8V output configuration before procurement. Confirm the component is sourced from authorized Microchip Technology distributors to ensure authenticity. Check datasheet specifications regarding lead finish and RoHS compliance against project requirements. Ensure proper handling precautions are observed due to ESD sensitivity.

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

Select this part when two distinct regulated rails are needed from a single power source in space-constrained designs. The MIC5371 variant is preferred over the MIC5370 if automatic output discharge is required during disable states. Verify that the input voltage remains within the 2.5V to 5.5V operating range for stable regulation. Consider the 90°C/W thermal resistance for ambient temperature calculations under full load conditions.

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

This component belongs to the MIC5370/1 family of advanced dual LDO regulators designed for portable devices. The MIC5371 series specifically incorporates an internal resistive load to discharge output capacitors when disabled, distinguishing it from the standard MIC5370. Both variants share identical electrical performance metrics and packaging dimensions.

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

MIC5370-SGYMT-TR serves as a functional substitute lacking the auto-discharge feature. Other MIC5371 variants with different voltage combinations may be used if the output requirements differ.

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

What is the difference between MIC5371 and MIC5370?

The MIC5371 includes an auto-discharge circuit that applies an internal resistive load to the outputs when disabled, whereas the MIC5370 does not have this feature.

Can the MIC5371 operate without a load?

Yes, the device remains stable and in regulation even with no load, which is beneficial for CMOS RAM keep-alive applications.
