LR12LG-G Integrated Circuits (ICs)

LR12LG-G is a linear voltage regulator solution, providing excellent output voltage accuracy, low dropout voltage, current limit and thermal shutdown protection. It offers a wide range of features, including over/under-voltage protection and over temperature protection, as well as a low quiescent current. The low dropout voltage and wide operating temperature range make it suitable for a variety of applications including automotive, industrial and process control. As an analog device, LR12LG-G can be used for both limiting and voltage step down applications.

In the application field, LR12LG-G is designed to be an ideal choice for automotive, industrial and process control applications due to its convenience of use, excellent electrical performance, and backup protection. It can be used in LED lighting and industrial motors, circuit protection, and power supply regulation. It is also applicable in a variety of applications, including low power power supplies, portable electronics, robots, and vision systems.

The working principle of the LR12LG-G is based on a bi-directional current flows between output and input, which are achieved by the action of the control channel and the current channel. In the controlled section, the control zone consists of two distributed resistors and a PMOSFET. In addition, there is a voltage reference connected between the input and ground to ensure the system is always in balance.

The output current is generated by applying the gate voltage of the P-type MOSFET to the control channel, which enables the current to flow across the current channel. Consequently, the current is limited and compared to the reference voltage, and the output is regulated to a constant voltage value. In addition, the LR12LG-G also provides a voltage-controlled architecture that can be configured to support both limiting and voltage step-down operations.

The LR12LG-G features a high power efficiency and a wide range of features, including over/under-voltage protection and over temperature protection. It also has an ultra-low quiescent current and a precise current limit output voltage. The wide operating temperature range also makes it suitable for a variety of applications.

In conclusion, the LR12LG-G is a linear voltage regulator solution that provides excellent output voltage accuracy, low dropout voltage, current limit and thermal shutdown protection.
