Overview
The LE25ABD is a linear voltage regulator IC from the LE00 series by STMicroelectronics. It provides a fixed positive output of 2.5V with a maximum load current of 100mA. The device features over-current and over-temperature protection. It operates within an input voltage range up to 30V and supports an operating temperature range of -40°C to 125°C. The component is housed in an 8-SOIC surface-mount package.
Feature Summary
- Fixed 2.5V output voltage regulation
- Integrated over-current and thermal protection
- Low dropout linear regulation capability
Applications
- Battery-powered portable devices
- General-purpose power supply conditioning
- Embedded system voltage reference
Procurement Notes
Verify the exact manufacturer part number against official STMicroelectronics documentation before procurement. Confirm that the LE25ABD designation matches the required electrical specifications and package type. Check for any specific ordering suffixes or revisions that may affect compatibility. Ensure the supplier provides valid traceability and authenticity guarantees for this component.
Selection Notes
Select the LE25ABD when a stable 2.5V rail is required for low-power applications. Consider its 100mA current limit and SO-8 package constraints. Evaluate if the fixed output voltage meets the target circuit requirements without additional adjustment components. Verify thermal management needs based on the expected voltage drop and load current.
Part Context
The LE25ABD belongs to the LE00 series of low-dropout regulators offered by STMicroelectronics. This series includes various output voltages and packages, such as TO-92 and SO-8. The LE25ABD specifically utilizes the 8-SOIC package, distinguishing it from through-hole variants within the same family.
Replacement Considerations
Consult official STMicroelectronics substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Generic equivalents may not match the specific protection features or thermal performance of the original component.
