Overview
The LE30CD is an 18V linear voltage regulator manufactured by STMicroelectronics. It operates in a surface-mount SOIC-8 package with dimensions of 5mm x 4mm x 1.65mm. The device supports a maximum input voltage of 18V and maintains operation up to a maximum junction temperature of 125°C. Quiescent current consumption is specified at 1.5mA. This component belongs to the LE30 series and is designed for positive polarity regulation applications.
Feature Summary
- Surface-mount construction in an 8-pin SOIC package
- Positive polarity voltage regulation capability
- Operates at elevated temperatures up to 125°C
Applications
- General purpose voltage regulation
- Embedded power supply circuits
Procurement Notes
Verify part authenticity through authorized STMicroelectronics distributors or certified suppliers. Confirm the specific suffix (e.g., TR) matches the required reel packaging configuration. Ensure the SOIC-8 footprint aligns with existing PCB layouts. Cross-reference the datasheet revision date to confirm parameter stability before finalizing procurement orders.
Selection Notes
Select this regulator when an 18V input limit and 125°C thermal rating are required. The 1.5mA quiescent current suits low-power designs. Verify that the SOIC-8 package fits the assembly constraints. Compare against other LE30 series variants if different output voltages or package types are needed for the specific application requirements.
Part Context
The LE30CD belongs to the LE30 series of linear regulators from STMicroelectronics. These devices provide stable voltage regulation for electronic circuits. The CD suffix typically denotes the SOIC-8 surface-mount package variant within this product family, offering a compact solution for board-level power management tasks.
Replacement Considerations
Consult official replacement guides for obsolete components. Identify equivalent regulators with matching pinouts and electrical specifications. Verify thermal performance and package compatibility before substitution.
