Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is STMicroelectronics to ensure component authenticity. Check RoHS compliance status via official documentation before integration. Validate the SOT-23-5 footprint compatibility with your PCB design. Ensure the 6V output variant matches your circuit requirements precisely.
Selection Notes
Select this component when a fixed 6V supply is required with minimal quiescent current. The integrated shutdown feature allows for effective power management in standby modes. Verify that the input voltage remains within the specified 2.5V to 14V range. Consider the thermal performance in the SOT-23-5 package under continuous load conditions. Ensure logic signals driving the enable pin are compatible with TTL or CMOS standards.
Part Context
This part belongs to the LK112S series of low-dropout regulators. It shares architectural similarities with other variants like LK112SM18TR but differs in output voltage and current ratings. The series emphasizes low noise and efficient power management for portable applications. Understanding the family context helps in selecting appropriate bypass capacitors and thermal management strategies.
Replacement Considerations
Direct substitutes include other LK112 series variants with matching output voltages. Cross-reference pinouts and electrical specifications carefully. Verify thermal resistance values if replacing in high-power scenarios. Ensure logic-level compatibility for the shutdown pin remains unchanged.
FAQ
How is the shutdown function activated?
The internal electronic switch is controlled by TTL or CMOS logic levels applied to the enable pin.
What is the maximum output current?
The device provides a maximum output current of 150 mA.
Does it support negative input voltages?
No, the input voltage range is specified from 2.5 V to 14 V, indicating positive operation only.
