MIC37301-2.5WR

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

The MIC37301-2.5WR is a fixed-output linear voltage regulator manufactured by Microchip Technology, designed for high-current applications. It provides a fixed output voltage of 2.5V with a maximum continuous output current of 3A. The device supports an input voltage range up to a maximum of 6V and operates within an extended temperature range from -40°C to +125°C. It utilizes the 5-SPAK surface-mount package, which integrates thermal management capabilities. Key control features include an enable pin for power management, while built-in protection mechanisms safeguard against overcurrent, thermal overload, and reverse polarity conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated thermal protection circuitry prevents damage during overheating events
• Reverse polarity protection allows safe connection even if input leads are swapped
• Enable pin functionality facilitates system power sequencing and standby modes

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

• Portable electronic devices requiring stable low-voltage power rails
• Industrial control systems operating in extreme temperature environments
• Automotive electronics modules needing robust reverse polarity tolerance

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

Verify the specific suffix 'WR' corresponds to the required tube packaging configuration, as other suffixes may indicate tape-and-reel options. Confirm RoHS compliance status aligns with project environmental requirements. Ensure the 5-SPAK footprint matches the PCB layout design. Validate that the 6V maximum input rating suits the source voltage profile under all transient conditions.

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

Select this component when a fixed 2.5V rail is necessary with up to 3A load capability. The 5-SPAK package offers superior thermal dissipation compared to smaller SOT packages. Consider the 6V input limit; higher input voltages require different regulators. The integrated protections reduce external component count. Verify the enable pin logic level compatibility with the controlling microcontroller or switch.

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

This part belongs to the MIC37301 series of high-current LDO regulators from Microchip. The series includes variants with different fixed output voltages, such as 1.5V and 3.3V, sharing the same 3A performance envelope and protective feature set. The 5-SPAK package is common across this family to ensure consistent thermal performance and mechanical mounting characteristics for industrial-grade applications.

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

MIC37301-3.3WR: Identical form factor and current rating but provides a fixed 3.3V output instead of 2.5V. MIC37301-1.5WR: Same package and protections but delivers a fixed 1.5V output. These parts share the same pinout and thermal characteristics, allowing for direct substitution if the voltage requirement changes.
