Overview
The LD2980CM25TR is a fixed-output linear voltage regulator manufactured by STMicroelectronics, delivering a constant 2.5V output with a maximum current capacity of 50mA. It operates within an input voltage range up to 16V and features a typical dropout voltage of 0.225V at full load. The device incorporates internal overcurrent and thermal shutdown protection mechanisms to ensure operational safety. It is housed in a compact SOT-23-5 surface-mount package and supports an extended operating temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low quiescent current consumption for efficient power management
- Compatible with low ESR ceramic output capacitors
- Logic-controlled electronic shutdown function via inhibit pin
- Internal current limiting and thermal overload protection
Applications
- Battery-powered portable systems
- Low noise instrumentation circuits
- Industrial control boards
- Audio system power supplies
Procurement Notes
Verify component status as the LD2980CM25TR is officially obsolete and no longer manufactured. Confirm availability of qualified replacement parts such as the LP2980AIM5-2.5/NOPB before finalizing design implementations. Ensure all sourcing channels provide genuine components compliant with RoHS3 standards to maintain regulatory adherence.
Selection Notes
Select this component for applications requiring stable regulation with ceramic capacitors and minimal static power draw. The fixed 2.5V output suits digital logic interfaces requiring precise reference voltages. Consider the SOT-23-5 footprint constraints and thermal dissipation requirements when designing PCB layouts for high ambient temperatures.
Part Context
This part belongs to the LD2980 family of ultra-low drop voltage regulators designed for low-power applications. The series emphasizes compatibility with modern low ESR ceramic capacitors while maintaining stability. The CM25 suffix specifically denotes the 2.5V fixed output variant within the broader LD2980 product line.
Replacement Considerations
The LP2980AIM5-2.5/NOPB by Texas Instruments is a documented similar substitute offering comparable electrical characteristics and pinout compatibility.
