MIC37501-1.5WR-TR

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

The MIC37501-1.5WR-TR is a fixed-output low dropout linear voltage regulator from Microchip Technology, providing a stable 1.5V output at up to 5A load current. It operates within an input voltage range supporting high differential voltages and features a typical dropout voltage of 280mV at full load. The device includes integrated thermal shutdown and current limiting protection. It is housed in a 7-SPAK surface-mount package designed for efficient heat dissipation, ensuring reliable operation across an extended temperature range of -40°C to +125°C.

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

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the 1.5V output variant matches the target circuit requirements. Ensure compatibility with the 7-SPAK footprint during PCB layout verification. Check for RoHS compliance status if required by manufacturing standards. Validate supplier authenticity through authorized distribution channels to prevent counterfeit parts.

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

Select this component when a fixed 1.5V rail is needed with high current demand exceeding standard LDO capabilities. Consider the 7-SPAK package for its superior thermal handling compared to smaller SOT packages. Evaluate input-to-output voltage differentials to ensure operation remains within safe thermal limits. Compare against adjustable variants if flexibility in output voltage is required instead of a fixed setting.

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

This part belongs to the MIC37501 series of high-current LDO regulators. The series is characterized by its ability to deliver substantial current while maintaining low noise and high power supply rejection ratios. The 7-SPAK package distinguishes it from lower-current counterparts, offering enhanced thermal dissipation for demanding applications where stability and reliability are critical under heavy loads.

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

Direct substitutes include other MIC37501 variants with different fixed output voltages such as MIC37501-1.8WR or MIC37501-2.5WR, provided the voltage requirement changes. Cross-brand replacements must match the 5A current rating, 7-SPAK package, and similar dropout characteristics. Verify pinout compatibility before substituting with non-Microchip equivalents.
