Overview
The L78L12CD13TR is a positive linear voltage regulator from the STMicroelectronics L78L series, providing a fixed 12 V output with a maximum current of 100 mA. It operates within an input voltage range up to 35 V and features internal thermal overload and short-circuit protection. The device utilizes an SO-8 surface-mount package and maintains operation across a temperature range of 0 °C to 125 °C.
Feature Summary
- Integrated thermal shutdown and current limiting for robust operation
- Requires no external components for basic regulation
- Available in ±8% output voltage tolerance selection
Applications
- Local on-card voltage regulation
- Noise elimination in single-point distribution systems
- Replacement for Zener diode and resistor combinations
Procurement Notes
Verify the specific suffix 'CD13' against official documentation to confirm the SO-8 tape-and-reel packaging and ±8% voltage accuracy grade. Ensure compatibility with the required operating temperature range and input voltage limits before finalizing procurement specifications.
Selection Notes
Select this component when a fixed 12 V supply is needed with moderate current requirements up to 100 mA. Consider the SO-8 package for surface-mount assembly and verify that the input voltage does not exceed the absolute maximum rating of 35 V under all operating conditions.
Part Context
This part belongs to the L78Lxx family of three-terminal positive regulators manufactured by STMicroelectronics. The series is designed for general-purpose applications requiring reliable voltage regulation without complex external circuitry, offering durability through built-in safety features.
Replacement Considerations
Compatible substitutes include other L78L12 variants such as L78L12ACD13TR or L78L12ABD13TR, provided the voltage tolerance and temperature range meet the design requirements.
