LK112SM17TR

The LK112SM17TR is a current-mode, non-comparator-based, linear voltage regulator that offers high performance and low noise in many electronic applications. It is designed with a continuous-current-limiting feature to protect against overloads and current spikes. The voltage drop over the regulator is nominal and guaranteed to be less than or equal to a specified maximum threshold. It is also tolerant of wide input voltages, which reduce the need for complex voltage-conversion circuits.

The LK112SM17TR can provide output voltages with a minimum range of 0.5V up to the rated maximum. It can also be used in AC and DC operating conditions, providing the output voltage adjusted within ±1% accuracy. The device operates in four modes: shutdown, standby, regulation, and soft start. In shutdown mode, the output is disconnected from the input power source through the enable pin. In standby mode, the output voltage is equal to the input voltage and is maintained at full load. In regulation mode, the output voltage is regulated and kept stable. Finally, in soft-start mode, the output voltage is gradually brought up to its regulated value. This helps in protecting the load from inrush current and helps prolong the life of the source.

The output voltage of the LK112SM17TR is either held constant or varied using an external resistive sensing network. A comparator senses the voltage drop across the two resistors, and this signal is used to regulate the voltage drop across the regulator. Depending on the design of the comparison circuit, the output voltage can either be clamped to a constant voltage or reduced to a voltage that is linearly tracked to the input voltage. The maximum output current of the regulator is usually limited by the RDS of the device.

The LK112SM17TR is ideal for a wide range of applications, with its adjustable output voltage, low noise, and less than ±1% output voltage accuracy. As it is both DC and AC compatible, it can be used in systems with switching power supplies, and also in applications with heavy load transients, such as home audio and video equipment. The device also includes over-voltage, over-current and over-temperature protection features, which ensure the safety and performance of the circuit.

The LK112SM17TR is also useful for designing circuits with adjustable functionality. Applications such as LCD display screens, data drivers, amplifiers, and microprocessors, which require precise voltage control, can benefit from the adjustable output of this device. It is also suitable for powering integrated circuits, such as microprocessors and FPGAs, which require a stable, accurate, and isolated power source. The device is also well suited for handheld and automotive applications. Its wide temperature range and low noise level make it suitable for sensitive, low-power systems.

The LK112SM17TR is a linear voltage regulator with a wide range of benefits and applications. It provides adjustable output voltage with a guaranteed accuracy of ±1% or better, low noise, and wide temperature range. It also includes protection features which ensure the safety and performance of the system. With its low cost, small size, and wide range of applications, the LK112SM17TR is an ideal device for many electronic system design needs.
