Procurement Notes
Verify the specific manufacturer designation and package type against official STMicroelectronics documentation before procurement. Confirm that the component meets the required environmental specifications for your application. Ensure compatibility with existing circuit designs regarding input voltage limits and thermal management requirements. Cross-reference datasheets to validate pin configurations and electrical characteristics.
Selection Notes
Select this component when a fixed 3V supply is required with moderate current demands. Consider the 8-SOIC package for space-constrained PCB layouts. Evaluate thermal dissipation needs based on the input-to-output voltage differential and load current. Ensure the operating environment falls within the specified temperature range for reliable performance.
Part Context
The LE30ABD belongs to the LE00 series of low-dropout regulators from STMicroelectronics. This series offers various fixed output voltages in both SO-8 and TO-92 packages. These regulators are designed for efficient power management in portable and industrial applications, providing stable voltage regulation with minimal external components.
Replacement Considerations
Consult official STMicroelectronics documentation for verified substitute part numbers. Do not assume cross-compatibility with other manufacturers' devices without validating electrical parameters and pinouts.
