- Fixed output voltage configuration ensures consistent power regulation
- High power supply rejection ratio minimizes input ripple impact
Applications
- Noise-sensitive sensor power supplies
- RF circuit biasing
- Portable battery-powered devices
Procurement Notes
Verify the specific suffix J2925R confirms the 2.925V fixed output variant. Confirm the FlipChip-4 package type matches your PCB footprint requirements. Check current lifecycle status as some listings indicate scheduled obsolescence. Ensure compatibility with your system's thermal management strategy given the small form factor.
Selection Notes
Select this component when a stable 2.925V rail is required with minimal noise interference. The 250mA current capability suits moderate load applications. Consider the 5.5V maximum input limit during design. The ultra-low noise characteristic is critical for audio or RF sections where signal integrity depends on clean power rails.
Part Context
This part belongs to the LDLN025 series from STMicroelectronics, which focuses on ultra-low noise LDO regulators. The series offers various fixed output voltages tailored for precision applications. The LDLN025J2925R specifically targets designs needing high PSRR and low quiescent current in a compact footprint.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-out and electrical specifications against potential alternatives before substitution.
