Overview
The LK112M13TR is a fixed-output linear voltage regulator manufactured by STMicroelectronics, delivering a nominal 1.3V output with a maximum continuous current of 150mA. It operates within an input voltage range up to 14V and features a low dropout characteristic. The device incorporates internal protection mechanisms including overcurrent limiting and thermal shutdown. It is housed in a compact SOT-23-5 surface-mount package and supports industrial operating temperatures from -30°C to +125°C.
Feature Summary
- Integrated enable control pin for power management
- Built-in overcurrent and thermal overload protection
- Low quiescent current consumption for efficiency
Applications
- Battery-powered portable electronic devices
- Embedded systems requiring stable low-voltage rails
- Industrial control modules
Procurement Notes
Verify the specific suffix 'M13' confirms the 1.3V fixed output variant. Confirm the 'TR' designation indicates tape-and-reel packaging. Check component status as sources indicate this part may be discontinued or obsolete; validate availability through authorized distributors before finalizing procurement plans.
Selection Notes
Select this component when a fixed 1.3V supply is required with moderate load currents up to 150mA. Ensure the input voltage remains within the 14V maximum limit. Consider the SOT-23-5 package constraints for thermal dissipation at higher loads. Verify that the -30°C to +125°C temperature range meets the application's environmental requirements.
Part Context
This component belongs to the LK112 series of low-dropout regulators from STMicroelectronics. The series offers various fixed output voltages and packages. The LK112M13TR specifically denotes the 1.3V output version in tape-and-reel format. It serves as a power management integrated circuit (PMIC) for stabilizing voltage levels in electronic circuits.
Replacement Considerations
Consult official STMicroelectronics documentation for direct cross-reference substitutes. Verify compatibility regarding output voltage, current capacity, and pin configuration before replacing.
