Overview
The LE25ABZ is a linear voltage regulator from STMicroelectronics, designed for fixed output applications. It utilizes a TO-92-3 through-hole package suitable for general-purpose power management. The device operates within an ambient temperature range of -40°C to +125°C and incorporates internal protection mechanisms against overcurrent and thermal overload conditions.
Feature Summary
- Fixed output voltage regulation via linear topology
- Integrated overcurrent and thermal shutdown protection
- Through-hole mounting in compact TO-92-3 package
Applications
- General purpose low-dropout power supply circuits
- Battery-powered equipment requiring stable voltage rails
- Industrial control systems operating in extended temperature ranges
Procurement Notes
Verify the specific suffix (e.g., TR) for tape-and-reel packaging requirements if applicable. Confirm the exact output voltage variant matches the design specification, as the base part number may represent a family. Ensure the TO-92-3 package orientation aligns with the PCB footprint. Check RoHS compliance status for environmental regulations.
Selection Notes
Select this component when a robust, through-hole linear regulator is required for moderate current applications. The wide operating temperature range supports industrial environments. Consider the thermal dissipation capabilities of the TO-92 package relative to the expected load current and ambient conditions to ensure reliable operation without external heatsinks.
Part Context
This part belongs to the L78Lxx series of positive linear voltage regulators manufactured by STMicroelectronics. These devices are widely used in consumer electronics and industrial applications due to their simplicity and reliability. The LE25ABZ specifically denotes a variant within this established line, offering standard regulatory functions in a traditional leaded package.
Replacement Considerations
Compatible substitutes include other L78Lxx series regulators from STMicroelectronics or equivalent fixed-output linear regulators from manufacturers such as ON Semiconductor or Texas Instruments, provided pinouts and electrical characteristics match.
