Overview
The STMicroelectronics L78L12ACZ-AP is a three-terminal positive linear voltage regulator delivering a fixed 12 V output with up to 100 mA current capability. It operates within an input voltage range of 14 V to 35 V and maintains stability across a junction temperature range of 0 °C to 125 °C. The device features internal thermal overload and short-circuit protection, eliminating the need for external components. Packaged in a TO-92-3 through-hole configuration, it provides reliable regulation for local or on-card applications.
Feature Summary
- Integrated thermal overload and short-circuit protection mechanisms ensure robust operation under fault conditions.
- Requires no external components for basic voltage regulation functionality.
- Designed as a direct replacement for Zener diode and resistor combinations with improved performance.
Applications
- Local or on-card voltage regulation
- Elimination of noise associated with single-point regulation
- Replacement for Zener diode/resistor networks
Procurement Notes
Verify the specific suffix 'AP' against official documentation to confirm packaging details, as ordering suffixes may indicate variations in tape-and-reel specifications or environmental compliance grades. Ensure compatibility with required operating temperatures and input voltage ranges before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 12 V output at 100 mA is required in a compact through-hole package. Consider the ±8% output voltage tolerance inherent to the 'C' designation. Evaluate thermal dissipation requirements based on the difference between input and output voltages and the maximum load current.
Part Context
This part belongs to the L78Lxx series of three-terminal positive regulators from STMicroelectronics. The series offers various fixed output voltages and is designed for general-purpose linear regulation applications requiring low cost and simplicity.
Replacement Considerations
LM78L12ACZ/LFT3 (Texas Instruments) is listed as a similar alternative.
FAQ
What is the output voltage tolerance for the L78L12ACZ-AP?
The 'C' designation indicates an output voltage tolerance of ±8%.
Does the L78L12ACZ-AP require external capacitors?
No external components are required for basic operation, though typical application circuits may include input and output capacitors for stability.
