Overview
The LF80ABPT-TR is a fixed-output linear regulator from STMicroelectronics, providing an 8V output with a maximum current of 500mA. It utilizes a PPAK package and operates within a temperature range of -40°C to +125°C. Key electrical characteristics include a quiescent current of 1.5mA and power supply rejection ratios ranging from 72dB at 120Hz to 57dB at 10kHz. The device features logic-controlled enable functionality for power management efficiency.
Feature Summary
- Fixed 8V output voltage regulation
- Logic-controlled enable pin for power switching
- High power supply rejection ratio across frequency ranges
Applications
- Embedded systems requiring stable 8V rails
- Industrial control circuits
- Consumer electronics power supplies
Procurement Notes
Verify the specific suffix and package type against the official datasheet to ensure compatibility with your PCB footprint. Confirm RoHS compliance status as indicated in the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component when a fixed 8V output is required with moderate current demands up to 500mA. Consider the PPAK package constraints and thermal dissipation requirements relative to your application's ambient temperature conditions.
Part Context
This part belongs to the LF series of low-dropout regulators manufactured by STMicroelectronics. It is designed for applications needing reliable linear regulation with minimal external components, fitting into broader power management solutions.
Replacement Considerations
Check for direct pin-compatible alternatives within the same LF series or comparable LDOs from other manufacturers offering identical 8V/500mA specifications and PPAK packaging.
