AMS1117-5.0

Overview

The EVVO AMS1117-5.0 is a positive low dropout linear regulator providing a fixed 5.0V output with a maximum current of 1A. It features a typical dropout voltage of 1.2V at full load and maintains an output accuracy within ±1.5%. The device includes on-chip thermal shutdown and current limiting protection, operating reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Fixed 5.0V output with ±1.5% tolerance
• Low dropout voltage operation down to 1.2V at 1A
• Integrated thermal shutdown and current limiting

Applications

• Battery chargers
• Portable instrumentation
• SMPS post-regulators
• Cellular phones

Procurement Notes

Verify the manufacturer designation matches EVVO specifications. Confirm the package type aligns with design requirements, as SOT-89-3L, SOT-223-3L, and TO-252-2L are available variants. Ensure compliance with RoHS standards and check for specific marking codes corresponding to the 5.0V fixed version.

Selection Notes

Select this component when a stable 5V rail is required from higher input voltages. Verify that the input-to-output differential remains above the minimum dropout threshold under all load conditions. Consider thermal resistance values for heat dissipation calculations in enclosed environments.

Part Context

This part belongs to the AMS1117 series of three-terminal LDO regulators designed for low-voltage applications. The series offers both fixed and adjustable versions, optimized for transient response and minimal input voltage requirements in portable and battery-powered systems.

Replacement Considerations

Compatible replacements include AMS1117-5.0 from other manufacturers such as Advanced Monolithic Systems Ltd or Shenzhen Slkormicro Semicon Co., Ltd., provided pinouts and electrical characteristics match.
