LK112M33TR ST Voltage Regulators - Linear

The LK112M33TR is a low-noise low-dropout linear voltage regulator from STMicroelectronics in SOT-23-5 package, providing fixed 3.3V output with up to 150mA current capability . For selection, verify input voltage from 4.3V to 9.3V (absolute maximum 16V), dropout voltage of 170mV typical (350mV max) at full load, output tolerance of ±1.8% (3.24V to 3.36V), quiescent current optimized for low power, line regulation of 0.04% max, load regulation of 0.09% max, 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 3.3V output with low noise and low dropout .
