Overview
The LDFM50DT-TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 5.0 V with a maximum output current of 500 mA. The device operates within an input voltage range of 2.6 V to 16 V and features a typical dropout voltage of 200 mV at full load. It includes internal protection mechanisms such as thermal shutdown and current limiting. The component is housed in a TO-252-5 surface-mount package and is rated for operation over an extended temperature range from -40°C to +125°C.
Feature Summary
- Fixed 5.0 V output voltage capability
- Integrated thermal shutdown and current limit protection
- Low quiescent current consumption
Applications
- Battery-powered portable devices
- Embedded systems requiring stable 5 V logic supply
- Industrial control modules
Procurement Notes
Verify the specific suffix DT-TR against official STMicroelectronics documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with the target PCB footprint, specifically the TO-252-5 outline. Cross-reference the datasheet revision date to validate electrical parameters against the manufacturing batch. Confirm RoHS compliance status through the manufacturer's official declaration before finalizing procurement.
Selection Notes
Select this component when a fixed 5.0 V rail is required with moderate current demands up to 500 mA. The low dropout characteristic makes it suitable for applications where the input voltage is close to the output level. Consider the thermal performance in the TO-252-5 package relative to the expected power dissipation. Verify that the input voltage does not exceed the 16 V maximum rating under all operating conditions.
Part Context
This part belongs to the LDFM series of low-dropout regulators from STMicroelectronics. The series is designed for general-purpose linear regulation applications. The LDFM50 variant specifically targets 5.0 V output requirements. It complements other fixed-voltage options within the same family, offering a balance between performance and cost for standard digital logic supplies.
Replacement Considerations
Direct substitutes include other 5.0 V LDOs in TO-252 packages from STMicroelectronics or compatible manufacturers. Verify pinout compatibility and thermal resistance values. Check if alternative parts meet the same 500 mA output current and 16 V input voltage specifications.
