Overview
The LD2982BM285R is a positive fixed-output linear voltage regulator from STMicroelectronics, delivering a precise 2.85 V output with ±1% tolerance at 25 °C. It supports a maximum load current of 50 mA and operates with an input voltage range up to 16 V. The device features a low dropout voltage of 0.225 V at full load. Packaged in a compact SOT-23-5 surface-mount case, it integrates internal current limiting and thermal shutdown protection for robust operation in space-constrained applications.
Feature Summary
- Provides a stable 2.85 V fixed output with high precision
- Operates with low dropout voltage for efficient power management
- Includes internal short-circuit and thermal overload protection
Applications
- Portable battery-powered electronic devices
- Low-power embedded systems requiring stable voltage rails
- Interface circuits needing regulated supply voltages
Procurement Notes
Verify the component status as obsolete before procurement planning. Confirm package integrity and pinout compatibility with existing PCB layouts. Ensure replacement strategies are established due to end-of-life status. Validate that alternative sources provide genuine components matching original specifications.
Selection Notes
Select this component only if a fixed 2.85 V output is required. Consider the 50 mA current limit for load requirements. Evaluate the SOT-23-5 footprint against available board space. Assess thermal performance under expected operating conditions given the small package size.
Part Context
This part belongs to the LD2982 series of low-dropout linear regulators. It is designed for applications requiring high ripple rejection and low quiescent current. The series typically offers various fixed output voltages to suit different digital logic families and sensor requirements.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source data. Due to the obsolete status, direct cross-referencing requires consulting official manufacturer substitution guides or authorized distributor databases for equivalent functional replacements.
