Overview
The LF80CPT-TR is a positive low-dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It provides a fixed 8 V output with a maximum continuous output current of 0.5 A. The device utilizes a TO-252-5 (DPAK) surface-mount package and operates within an extended temperature range from -40 °C to +125 °C. Key electrical specifications include a typical dropout voltage of 0.45 V at full load, a quiescent current of 50 µA, and a line regulation of 25 mV. The unit features a single output channel with a voltage accuracy of ±2%.
Feature Summary
- Very low dropout voltage capability for efficient power conversion
- Low quiescent current consumption suitable for battery-powered systems
- Integrated thermal protection and short-circuit current limiting
Applications
- Battery-powered portable electronic devices
- Low-noise analog circuit power supplies
- General-purpose low-power embedded systems
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm the manufacturer part number matches exactly as LF80CPT-TR to ensure correct output voltage and package type. Check for RoHS compliance documentation if required for your assembly process. Ensure the supplier is authorized to guarantee component authenticity.
Selection Notes
Select this component when an 8 V rail is required with moderate current demands up to 0.5 A. The low dropout characteristic makes it suitable for applications where input voltage is close to the output level. Consider the TO-252-5 package for its thermal performance in surface-mount designs. Verify that the input voltage does not exceed the absolute maximum rating specified in the datasheet.
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 applications. The LF80 variant specifically targets 8 V regulation needs within this family, sharing common architectural features such as high ripple rejection and robust protection mechanisms against thermal overload.
Replacement Considerations
Compatible substitutes within the same series include LF50CPT-TR (5 V output) or LF18CPT (1.8 V output) if voltage requirements differ. Cross-brand replacements require matching pinout, current capacity, and dropout voltage characteristics. Always verify thermal dissipation capabilities and package dimensions before substituting.
