Overview
The LF30CDT-TR is a linear voltage regulator IC manufactured by STMicroelectronics. It provides a fixed 3V output with a maximum current capacity of 500mA. The device belongs to the LE30 series and features very low drop voltage regulators with inhibit functionality. It is designed for surface mount installation in DPAK packages.
Feature Summary
- Provides a fixed 3V output voltage
- Supports up to 500mA load current
- Includes inhibit control functionality
- Designed as a very low drop voltage regulator
Applications
- Consumer electronic devices requiring stable 3V power
- Battery-powered systems needing efficient regulation
- General purpose linear voltage regulation circuits
Procurement Notes
Verify the exact package type, as sources indicate DPAK for LF30CDT but SOIC for similar LE30 variants. Confirm the manufacturer is STMicroelectronics. Check for RoHS compliance status. Ensure the inhibit feature is required for the specific application design. Validate the 500mA current rating against thermal constraints.
Selection Notes
Select this component when a fixed 3V output is required with moderate current demands up to 500mA. The inhibit feature allows for power management control. Consider thermal dissipation requirements due to linear regulation nature. Compare with other LE30 series variants if different voltages or packages are needed.
Part Context
This part belongs to the LE30 series of very low drop voltage regulators from STMicroelectronics. These regulators are designed for applications requiring stable voltage supply with minimal dropout voltage. The series includes various output voltages and packages to suit different design needs.
Replacement Considerations
Check for direct substitutes within the LE30 series offering the same 3V output and 500mA capability. Verify pin compatibility and package dimensions before substitution. Ensure equivalent inhibit functionality is present in alternative parts.
