MIC5209-1.8YU

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

The MIC5209-1.8YU is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Microchip Technology. It provides a stable 1.8V output with a maximum current capacity of 500mA. The device features a dropout voltage of 0.6V at full load and operates within an input voltage range up to 16V. It includes integrated protection mechanisms such as overcurrent, thermal shutdown, and reverse polarity protection. The component is housed in a TO-263-5 (D2PAK-5) surface-mount package and supports operation across a temperature range of 0°C to 125°C.

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

Verify the specific suffix 'YU' corresponds to the TO-263-5 package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the ordering part number matches the required tape-and-reel or tube packaging format for your assembly process.

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

Select this component when a fixed 1.8V rail is required with moderate current demands up to 500mA. The TO-263-5 package offers improved thermal dissipation compared to smaller SOT packages. Consider the 0.6V dropout characteristic against your minimum input voltage headroom requirements.

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

This part belongs to the MIC5209 family of LDO regulators from Microchip Technology. The family shares common architectural features including low noise and robust protection circuits. Variants differ primarily by output voltage and physical package type, such as SOIC or D2PAK configurations.

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

Direct substitutes include other MIC5209 variants with different output voltages if the voltage level can be adjusted. Cross-brand replacements require matching the 500mA current rating, 1.8V output, and TO-263-5 footprint while verifying pin compatibility.
