Quality Control: Learn More
The STMicroelectronics LK112SM55TR is a positive fixed output linear voltage regulator IC. This device delivers a stable 5.5V output with a maximum current capability of 200mA. It features an enable pin for enhanced control and protection against over current and over temperature conditions. The typical quiescent current is 250µA, and it offers a high power supply rejection ratio (PSRR) of 55dB at 400Hz, making it suitable for noise-sensitive applications. With a maximum input voltage of 14V and a dropout voltage of 0.5V at 200mA, this component is supplied in a SOT-23-5 package, suitable for surface mounting. Applications include consumer electronics, industrial automation, and portable devices.
