Overview
The LK112M36TR is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 3.6V output with a maximum current capacity of 150mA. It operates within an input voltage range of 2.5V to 14V and features a low dropout voltage of 500mV at full load. The device maintains a quiescent current of 250µA and offers protection against over-current and over-temperature conditions. It is housed in a compact SOT-23-5 package and supports operation across a temperature range of -40°C to +125°C.
Feature Summary
- Provides precise fixed output regulation for stable power delivery
- Includes built-in thermal and current protection mechanisms
- Designed for surface-mount installation in space-constrained applications
Applications
- Battery-powered portable electronics requiring efficient voltage regulation
- Embedded systems needing stable 3.6V logic supply rails
- Industrial control modules operating in extended temperature environments
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolete lifecycle indicators, as availability may be limited. Ensure packaging specifications match production requirements before finalizing orders.
Selection Notes
Select this regulator when a fixed 3.6V output is required with moderate current demands up to 150mA. Consider the SOT-23-5 footprint for PCB layout constraints. Evaluate thermal performance under expected load conditions to ensure reliable operation within the specified temperature range.
Part Context
This component belongs to the LK112S series of low-dropout regulators manufactured by STMicroelectronics. These devices are part of the PMIC category, designed for general-purpose voltage regulation tasks in consumer and industrial electronics where efficiency and compact size are prioritized.
Replacement Considerations
Check for compatible alternatives within the same LDO family offering similar voltage and current ratings. Verify pin compatibility and thermal characteristics before substitution. Consult official datasheets for cross-reference information regarding equivalent parts.
