MIC47100-08YMME

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

The MIC47100-08YMME is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by Microchip Technology. It provides a fixed output voltage of 0.8 V with a maximum continuous output current of 1 A. The device operates within an input voltage range of 1 V to 3.6 V and features a typical dropout voltage of 80 mV at full load, with a maximum specified dropout of 250 mV. It incorporates internal protection mechanisms including overcurrent limiting, thermal shutdown, and under-voltage lockout (UVLO). The component is housed in an 8-lead MSOP package with an exposed pad (MSOP-EP) for enhanced thermal performance.

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

Verify the specific suffix '08' confirms the fixed 0.8 V output variant, as other suffixes indicate adjustable or different fixed voltages. Confirm the 'YMME' designation corresponds to the 8-MSOP-EP package with an exposed thermal pad. Ensure compliance with RoHS3 standards if required by your manufacturing process. Check moisture sensitivity level (MSL 3) requirements for storage and reflow soldering profiles.

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

Select this part when a precise 0.8 V rail is required without external resistor networks needed for adjustable regulators. Consider the 1 A current rating against peak load demands to ensure adequate thermal management. Evaluate the input voltage range to guarantee sufficient headroom above the 0.8 V output while staying within the 3.6 V maximum limit. Compare dropout characteristics against load conditions to maintain regulation stability.
