Overview
The LF80ABV is a fixed-output linear voltage regulator from the LF series, manufactured by STMicroelectronics. It provides a stable 8.0 V output with a maximum continuous current of 100 mA. The device utilizes a SOT-89 surface-mount package and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 45 dB at 120 Hz, a quiescent current of 6 mA, and line regulation of 175 mV. It features internal thermal overload and short-circuit protection for robust operation.
Feature Summary
- Integrated thermal overload and short-circuit protection mechanisms ensure operational safety under fault conditions.
- High power supply rejection ratio effectively attenuates input ripple and noise for clean output voltage.
- Fixed positive output configuration simplifies circuit design without external feedback components.
Applications
- General-purpose linear voltage regulation in industrial electronics
- Power management for motor control applications
- Biasing circuits in standard semiconductor systems
Procurement Notes
Verify the specific ordering suffix against the official datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit products. Confirm that the thermal performance ratings align with your system's ambient operating conditions.
Selection Notes
Select this component when a fixed 8 V output is required with moderate current demands up to 100 mA. The SOT-89 package is suitable for space-constrained surface-mount designs. Consider the 6 mA quiescent current if power efficiency is a priority compared to lower-current alternatives. Verify input voltage limits do not exceed the maximum rating to prevent device damage.
Part Context
This regulator belongs to the LF family of very low drop voltage regulators produced by STMicroelectronics. The LF series is designed for applications requiring stable voltage conversion with minimal heat dissipation. The LF80ABV specifically targets the 8 V output segment, offering reliability through integrated protection features common to this product line.
Replacement Considerations
Consult official cross-reference data for compatible substitutes. Generic equivalents may differ in thermal resistance or pinout configuration. Verify that any replacement maintains the same output voltage polarity and current capacity.
