Overview
The LF80CDT-TR is a very low drop voltage regulator (LDO) manufactured by STMicroelectronics, providing a fixed positive output of 8 V. It supports an output current of 0.5 A with a maximum input voltage range from -0.5 V to 40 V. The device features a low dropout voltage of 0.45 V and includes an integrated on-off switch for power control. Packaged in a 3-pin DPAK (TO-252) with thermal tab, it is designed for surface-mount applications.
Feature Summary
- Integrated ON/OFF switch for precise power management
- Very low dropout voltage suitable for battery-powered systems
- Low quiescent current for energy efficiency
Applications
- Battery powered systems
- Low-noise applications
- Low-power applications
Procurement Notes
Verify the specific package type and tape-and-reel configuration against the manufacturer's datasheet before procurement. Confirm that the 8V output variant matches the design requirements. Ensure compatibility with the intended PCB footprint for the DPAK package. Check for any updated environmental compliance documentation.
Selection Notes
Select this component when a fixed 8V output is required with high efficiency under low voltage differentials. The integrated switch allows for system-level power gating without external components. Consider the thermal performance of the DPAK package for heat dissipation needs in the target application environment.
Part Context
This part belongs to the LFXX series of very low drop regulators from STMicroelectronics. The series offers various fixed output voltages optimized for low-noise and low-power environments. The LF80CDT-TR specifically targets applications requiring stable regulation with minimal voltage loss across the regulator.
Replacement Considerations
Check for direct pin-compatible alternatives within the same LF series family if different output voltages are needed. Verify that substitute parts maintain the same 0.5A current rating and DPAK packaging constraints.
