Overview
The LF27CDT-TR is a very low drop voltage regulator (LDO) manufactured by STMicroelectronics, featuring an inhibit control function. It provides a fixed output voltage of 2.7V with a maximum load current capability of 500mA. The device is housed in a DPAK surface-mount package, designed for efficient power management applications requiring stable regulation and low dropout performance under varying load conditions.
Feature Summary
- Provides a fixed 2.7V regulated output voltage
- Supports up to 500mA load current
- Includes an inhibit control pin for power management
- Designed as a very low drop voltage regulator
Applications
- Battery-powered portable devices
- Low dropout power supply circuits
- Embedded system voltage regulation
- Inhibit-controlled power distribution networks
Procurement Notes
Verify the part number suffix -TR indicates tape and reel packaging configuration. Confirm the DPAK package type matches your PCB footprint requirements. Ensure the 2.7V output voltage aligns with your target circuit design specifications before procurement.
Selection Notes
Select this component when a fixed 2.7V output is required with moderate current demands up to 500mA. The inhibit feature allows for system-level power control. Consider thermal dissipation capabilities in the DPAK package for high-load scenarios.
Part Context
This LDO belongs to STMicroelectronics' family of very low drop voltage regulators with inhibit functionality. It complements other fixed-output variants within the same series, offering a balance of efficiency, compact packaging, and control features for modern electronic designs.
Replacement Considerations
Check for compatible LDOs with similar 2.7V output and 500mA current ratings. Verify pinout compatibility if substituting directly. Ensure equivalent inhibit functionality and thermal performance in alternative packages.
