Overview
The LF90CPT-TR is a fixed 9V low-dropout linear voltage regulator from the LFXX series, manufactured by STMicroelectronics. It delivers an output current of up to 500 mA with a very low dropout voltage of 0.45 V. The device features a typical quiescent current of 0.7 mA and includes a logic-controlled electronic shutdown (inhibit) function. Packaged in a surface-mount PPAK format, it is designed for efficient power management in space-constrained applications requiring stable voltage regulation.
Feature Summary
- Very low dropout voltage operation for high efficiency
- Logic-controlled electronic shutdown capability
- Low quiescent current consumption
- Fixed 9V output voltage regulation
Applications
- Battery-powered portable electronics
- Embedded systems requiring stable 9V supply
- Space-constrained surface-mount designs
Procurement Notes
Verify the specific suffix (e.g., -TR for tape and reel) against your manufacturing requirements. Confirm the package type matches your PCB footprint. Ensure the fixed 9V output aligns with system design needs. Check RoHS compliance status if required by your region. Validate lead times with authorized distributors as availability may vary.
Selection Notes
Select this component when a fixed 9V output is required with minimal voltage drop under load. Consider the 500 mA current limit for load capacity. The inhibit feature allows for power saving modes. Ensure thermal management suits the PPAK package constraints. Verify input voltage range exceeds the dropout requirement plus 9V.
Part Context
This part belongs to the LFXX series of low-dropout regulators from STMicroelectronics. It is designed for applications needing reliable linear regulation with low power consumption. The series offers various fixed output voltages and current ratings. The LF90CPT variant specifically targets 9V applications in compact surface-mount packages.
Replacement Considerations
Check for direct pin-compatible alternatives within the same LFXX series offering different output voltages or currents. Verify that any substitute maintains the 500 mA output current and low dropout characteristics. Ensure the replacement supports the inhibit function if power control is critical.
