LK112SM50TR ST Voltage Regulators - Linear

The LK112SM50TR is a low-noise low-dropout linear voltage regulator from STMicroelectronics in SOT-23-5 surface-mount package, providing fixed 5.0V output with up to 150mA current capability. For selection, verify input voltage from 5.5V to 16V (absolute maximum 16V), dropout voltage of 170mV typical at 150mA load, output tolerance of ±1.8%, quiescent current optimized for low power, and operating temperature from -40°C to +125°C. Features include shutdown capability for power management, stable operation with low-ESR capacitors, and internal current and thermal protection. Ideal for mobile phones, laptops, consumer electronics, power management in portable devices, voltage regulation for DSPs and microcontrollers, battery charging circuits, and any space-constrained application requiring stable 5V output with low noise and low dropout.
