Overview
The AMS1117-5.0 SOT-89 is a positive fixed-output linear regulator manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It provides a nominal output voltage of 5.0V, with an operational range between 4.9V and 5.1V. The device supports a maximum output current of 1A and features a maximum dropout voltage of 1.3V at full load. It accepts input voltages up to 18V and includes internal current limiting and thermal shutdown protection. The component operates within a junction temperature range up to 150°C and utilizes the SOT-89 surface-mount package.
Feature Summary
- Provides stable 5.0V fixed output with ±1.5% accuracy
- Supports 1A continuous load current capability
- Integrates overcurrent and thermal shutdown protection mechanisms
Applications
- Microcontroller unit (MCU) power supply
- Sensor circuit powering
- Wireless module power management
Procurement Notes
Verify manufacturer origin as Shenzhen Slkormicro Semicon Co., Ltd. Confirm SOT-89 package type and 5.0V fixed output specification. Ensure RoHS compliance status matches project requirements. Validate datasheet version for accurate electrical parameters before integration.
Selection Notes
Select this component when a 5V rail is required from higher input sources. Ensure input voltage does not exceed 18V. Verify thermal dissipation capabilities in the target PCB layout due to SOT-89 package constraints under 1A load conditions.
Part Context
This part belongs to the AMS1117 series of low-dropout linear regulators. It shares functional similarities with other variants in the family but is specifically configured for a fixed 5.0V output. The SOT-89 package offers a compact surface-mount solution suitable for space-constrained designs compared to larger through-hole alternatives.
Replacement Considerations
Compatible substitutes include AMS1117-5.0 from other manufacturers such as STMicroelectronics or ON Semiconductor, provided pinouts and electrical specifications match. Verify thermal performance and package dimensions before substitution.
