LK115D30-TR is a linear voltage regulator product manufactured by LG Semiconductor. It is part of the LG’s Linear voltage regulator series. It is a dual channel device, featuring two separate outputs, which can be configured independently to supply different voltages.

The LK115D30-TR is a cost-effective and efficient voltage regulator, that is well suited for many different types of applications. Its dual channel outputs make it ideal for applications which require multiple supply rails such as set-top boxes, DVD players, and other consumer electronic devices. It is also an excellent choice for Power over Ethernet (PoE) applications and automotive systems.

The LK115D30-TR features a wide input voltage range (2.5V to 18V) and two adjustable output voltages with a range of 0.8V to 10V. The output current capability is up to 1A per channel and can be set to run in either constant current or constant voltage mode. The LK115D30-TR also has a wide operating temperature range (-40°C to +125°C) and has over-current and thermal shut-down protection.

The LK115D30-TR is a monolithic integrated circuit designed to provide a simple and convenient way to regulate voltage. The device consists of an error amplifier, a voltage reference, and an output control circuit. The ramp-based control circuitry ensures excellent line and load regulation, while the internal voltage reference provides temperature compensation.

The voltage setting can be adjusted by connecting an external resistor network to the device’s pins. The reference voltage is then set by the resistor divider network, and can also be adjusted by either adding or removing resistors. The error amplifier monitors the output voltage and provides a suitable correction signal to the output control circuitry.

The LK115D30-TR is a highly efficient, low power consumption device. It has a quiescent current of 300µA and an operating temperature range of -40°C to +125°C. The device is also protected against over-current and thermal shut-down.

The LK115D30-TR is suitable for many consumer and industrial applications requiring a low cost, efficient and reliable linear voltage regulator. It is ideal for applications such as set-top boxes, DVD players and other consumer electronic devices; as well as Power over Ethernet (PoE) applications and automotive systems. With its wide range of features, adjustable output voltage and excellent current handling capability, the LK115D30-TR is an ideal choice for cost-sensitive and power-efficient applications.
