Overview
The LD2985BM50R is a fixed output voltage regulator from STMicroelectronics, providing a stable 5 V DC output with a maximum load current of 150 mA. It operates within an input voltage range of 2.5 V to 16 V and features a very low dropout voltage of 0.575 V at full load. The device incorporates logic-controlled electronic shutdown via a TTL-compatible inhibit pin, allowing for reduced power consumption in standby modes. It includes internal protections against overcurrent and thermal overload, ensuring reliable operation across a temperature range of -40 °C to +125 °C.
Feature Summary
- Logic-controlled electronic shutdown function compatible with TTL levels
- Internal current limiting and thermal protection mechanisms
- Ultra-low quiescent current capability for battery-powered systems
Applications
- Cellular phones
- Palmtop laptop computers
- Personal digital assistants (PDA)
- Camcorders and cameras
Procurement Notes
Verify the specific suffix 'BM50R' to confirm the 5 V fixed output variant and SOT-23-5L package configuration. Ensure compatibility with required PCB footprint dimensions and thermal dissipation requirements for the target application environment.
Selection Notes
Select this component when a fixed 5 V supply is required with minimal voltage drop under high load conditions. Consider its low noise characteristics and shutdown functionality for portable electronics where power efficiency and board space are critical constraints.
Part Context
This part belongs to the LD2985 series of ultra-low-dropout linear regulators designed for low-noise applications. The series offers various fixed output voltages and shares common features such as small packaging and robust protection circuits, making it suitable for diverse consumer electronics.
Replacement Considerations
Direct substitutes include other LD2985 variants with different output voltages if system design allows adjustment, or equivalent LDO regulators from STMicroelectronics offering similar current ratings and package types.
