The LK112SM40TR is a linear voltage regulator. It is a low noise low drop-out voltage regulator that is characterized by its excellent ripple rejection, low temperature stability and a fast transient response which makes it an ideal choice for any application that requires a clean, reliable and stable power supply. It is a three-terminal device with low quiescent current and low dropout voltage.

The linear voltage regulator is a type of voltage regulator that is simple and inexpensive to use. It is used to maintain a constant output voltage over a wide range of input voltages and load conditions. It does this by monitoring the voltage drop across a series resistor, and by adjusting the base current of a regulating transistor in order to control the output voltage. This ensures extremely low output ripple, with very good overall accuracy.

The LK112SM40TR is widely applicable in consumer, communications and industrial applications such as active filter, DC/DC convertors, pre-regulators, battery-powered devices, medical instrumentation, dc power supply, etc. It is also used in applications where high EMI or low noise is required, such as video systems, laptop computers, GPS receivers, and industrial process control. It is designed to provide low noise, fast transient response, and excellent ripple rejection.

The LK112SM40TR\'s input voltage is typically between 2.2V and 45V, allowing it to be used with a wide variety of battery-power sources and dc/dc convertors. The output voltage is adjustable from 0.8V to 5.0V through an external resistor. The LK112SM40TR has an internal operating temperature range of -40°C to 85°C, as well as an ultra-low supply current of 90μA at 25°C and 40μA at 85°C. This makes it an efficient and low-power choice for many applications.

The LK112SM40TR offers a wide range of features, including auto-reset circuitry to protect against reverse loads, over-temperature protection, and C-load current limit protection. It also includes Thermal Shutdown and Current-Limit Threshold Adjustment capabilities and a 0.5Ω typical full load power dissipation.

The LK112SM40TR is a low drop-out regulator, capable of supplying up to 1A of output current. It has a wide output voltage range, making it suitable for a variety of input-to-output voltage conversions. Additionally, it features internally compensated error amplifiers and flexible input/output logic pins.

The LK112SM40TR is an excellent example of a linear voltage regulator. It is a reliable and stable choice for any application that requires clean, low-noise and accurate power regulation. Its wide input voltage range, low quiescent current, wide range of features, and fast transient response make it a suitable choice for a range of consumer, communications and industrial applications.
