Overview
The LE80CD-TR is a positive fixed linear voltage regulator manufactured by STMicroelectronics, delivering a nominal output of 8V at up to 100mA. It operates within an input voltage range of up to 18V and features a maximum dropout voltage of 0.5V at full load. The device includes enable control functionality and offers power supply rejection ratios ranging from 72dB at 120Hz to 57dB at 12kHz. It incorporates overcurrent and overtemperature protection mechanisms and functions reliably across an extended temperature range of -40°C to +125°C.
Feature Summary
- Provides stable regulated output with integrated overcurrent and thermal shutdown protection for circuit safety.
- Features low dropout characteristics enabling efficient operation with minimal input-to-output voltage differential.
- Includes an enable pin for precise power management and system-level control.
Applications
- Battery-powered systems requiring efficient voltage regulation
- General-purpose linear power supplies
- Post-regulation stages in switching power architectures
Procurement Notes
Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm package integrity upon receipt, noting the 8-SOIC form factor. Review official documentation for any product change notices or end-of-life directives that may impact long-term availability or sourcing strategies.
Selection Notes
Select this component when a fixed 8V output is required with moderate current demands up to 100mA. Ensure the input voltage does not exceed the 18V maximum rating. Consider the thermal performance in the 8-SOIC package relative to ambient conditions and PCB copper area for adequate heat dissipation during continuous operation.
Part Context
This device belongs to the LE series of low-dropout regulators from STMicroelectronics. It is designed for applications requiring simple, cost-effective linear regulation with built-in protection features. The SOIC-8 packaging facilitates surface-mount assembly in compact electronic designs.
Replacement Considerations
Consult manufacturer documentation for direct cross-references. Verify pin compatibility and electrical specifications before substituting with other LDO regulators offering similar voltage and current ratings.
