Overview
The LE80ABD-TR is a positive fixed linear voltage regulator from the STMicroelectronics LE80 series. It provides an 8V output with a typical dropout voltage of 0.2V at 100mA and a maximum of 0.5V at the same current. The device supports an input voltage up to 18V and operates within a temperature range of -40°C to +125°C. Packaged in an 8-SOIC format, it functions as a low-dropout (LDO) regulator designed for stable power supply applications.
Feature Summary
- Positive fixed output configuration
- Low dropout voltage operation
- Wide operating temperature range
Applications
- General purpose power supply regulation
- Battery-powered equipment voltage stabilization
- Embedded system power management
Procurement Notes
Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm package integrity and marking consistency against official datasheet specifications. Check lifecycle status as the part may be obsolete; ensure availability aligns with long-term production requirements before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 8V output is required with minimal voltage drop under load. Ensure input voltage does not exceed 18V. Consider thermal dissipation capabilities based on ambient temperature and load current. Verify that the 8-SOIC package fits the design constraints and that the operating temperature range meets environmental specifications.
Part Context
This component belongs to the LE80 series of low-dropout regulators manufactured by STMicroelectronics. The series offers various output voltages in SO-8 and TO-92 packages. The LE80ABD-TR specifically denotes the 8V variant in tape-and-reel packaging, intended for automated surface-mount assembly processes.
Replacement Considerations
Check for direct pin-compatible substitutes within the LE80 series offering different output voltages if voltage adjustment is needed. Verify equivalent LDO regulators from other manufacturers ensuring matching input/output voltage ranges, current capacity, and package dimensions for seamless integration.
