Overview
The LD1086D2M33TR is a positive fixed low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 3.3V with a maximum continuous output current of 1.5A. The device features a maximum input voltage rating of 30V and operates within a junction temperature range of -40°C to +125°C. Dropout voltage is guaranteed at a maximum of 1.2V at full load. The component utilizes a D2PAK-3 surface-mount package, integrating internal thermal overload and short-circuit protection mechanisms for robust performance in power management applications.
Feature Summary
- Provides stable 3.3V fixed output voltage with high current capability up to 1.5A
- Low dropout characteristic ensures efficient regulation under varying load conditions
- Integrated thermal overload and short-circuit protection safeguards against fault conditions
Applications
- Battery-powered systems requiring efficient voltage regulation
- Post-regulation stages for switching power supplies
- General-purpose power supply circuits in consumer electronics
Procurement Notes
Verify the specific suffix 'D2M33TR' corresponds to the 3.3V fixed output variant in the D2PAK-3 package. Confirm that the manufacturer's datasheet specifies the exact dropout voltage and thermal characteristics for your operating environment. Ensure compatibility with PCB footprint requirements for the TO-263AB/D2PAK outline before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3.3V rail is required with up to 1.5A load capacity. Consider the D2PAK package for its thermal dissipation capabilities compared to smaller SOT packages. Evaluate the input voltage range to ensure it remains within the 30V maximum limit while maintaining sufficient headroom above the 3.3V output for proper regulation.
Part Context
This part belongs to the LD1086 series of low-dropout positive voltage regulators from STMicroelectronics. The series includes both adjustable and fixed output versions available in various packages such as TO-220, TO-263 (D2PAK), and TO-252 (DPAK). The LD1086 family is designed for applications requiring high efficiency and low quiescent current, serving as a reliable solution for linear regulation tasks.
Replacement Considerations
Direct substitutes include other LD1086 variants with matching output voltages and packages, such as LD1086D2MxxTR where xx denotes the desired voltage. Cross-brand equivalents should be evaluated based on pinout compatibility, current rating, and thermal performance specifications.
