Overview
The LD29300P2M is a high current, high accuracy, low-dropout voltage regulator from the STMicroelectronics LD29300 series. It features a typical dropout voltage of 400mV at 3A and very low ground current. The device guarantees an output current up to 3A with fixed voltage options offering ±1% tolerance at 25°C. It includes internal current and thermal limiting protection and supports logic-controlled electronic shutdown in the PPAK package.
Feature Summary
- High current capability designed for demanding loads
- Very low dropout voltage for efficiency
- Internal current and thermal limit protection
- Logic controlled electronic shutdown
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Series power supply for VCRs and TVs
- Computer systems
- Battery powered systems
Procurement Notes
Verify the specific output voltage suffix (e.g., 15, 18, 25) required for your design, as the base part number covers multiple fixed voltages. Confirm the package type matches your PCB layout requirements. Check for any RoHS compliance status updates on the manufacturer's website before finalizing procurement.
Selection Notes
Select this component when high output current near 3A is needed with minimal voltage drop. Ensure input voltage stays within the 30V absolute maximum rating. Consider thermal resistance values for heat dissipation planning. Verify if the adjustable version or a specific fixed voltage variant better suits the application needs.
Part Context
This part belongs to the LD29300 series of 3A very low drop voltage regulators. The series offers various fixed output voltages and an adjustable option. It is designed for applications requiring high accuracy and low quiescent current. The P2M suffix indicates the P2PAK package configuration.
Replacement Considerations
Check for direct substitutes within the same LD29300 family with different voltage outputs or packages. Verify pin compatibility and thermal characteristics before substituting with other LDO regulators.
