LF27ABDT-TR

Overview

The LF27ABDT-TR is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 2.7V output with a maximum current capacity of 500mA. It operates within an input voltage range up to 16V and features a low dropout characteristic, specified at a maximum of 0.7V when delivering full load current. The device is housed in a surface-mount DPAK package, designed for efficient thermal performance and compact board integration.

Feature Summary

• Provides a fixed 2.7V regulated output voltage
• Supports continuous load currents up to 500mA
• Features low dropout operation for efficiency
• Includes inhibit functionality for power management

Applications

• Battery-powered portable devices requiring stable low voltage rails
• Embedded systems needing precise 2.7V logic supply
• Industrial control modules utilizing LDO regulation

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging configuration. Confirm the DPAK footprint matches your PCB layout requirements. Ensure input voltage does not exceed 16V to prevent device damage. Check thermal dissipation capabilities under maximum load conditions.

Selection Notes

Select this component when a fixed 2.7V output is required with moderate current demands. It is suitable for applications where space constraints favor the DPAK package over through-hole options. Consider thermal resistance if operating near maximum current limits.

Part Context

This part belongs to the LF27A series of very low drop voltage regulators. It is manufactured by STMicroelectronics and is categorized under linear voltage regulators. The series is known for integrating inhibit pins for enhanced system power control.

Replacement Considerations

Direct substitutes include other 2.7V 500mA LDOs in DPAK packages. Verify pinout compatibility and thermal characteristics before substitution.
