The LD112PV12R is a linear regulator that provides improved in-rush current response, higher switching frequency acceptance, and improved Standby Mode operation. Specifically, it is constructed with an input voltage range of 3.3 V to 21 V and an output voltage range of 0.7 V to 15 V. In addition, it offers adjustable soft start, an internal low voltage dropout, temperature monitoring and protection, as well as adjustable overvoltage protection. Furthermore, the LD112PV12R is designed to provide high accuracy, excellent transient response, and low noise performance.

The LD112PV12R is commonly used in automotive and industrial applications. It can be used to provide power for internal systems, such as navigation systems and control systems, as well as systems that require precise input/output, such as medical applications. It is also used in various power supplies and battery management, as well as liquid crystal displays (LCDs).

The addition of the linear regulator to the distribution system ensures the stability of the output. This is achieved by the regulator recognizing any sudden change in impedance introduced by the connected load. It is then able to adjust the voltage gain to maintain a constant output voltage, regardless of the load. As a result, the regulator offers improved overload protection and enhanced circuit performance.

In order for the linear regulator to provide this improved performance and protection, it must be employed properly. When using the LD112PV12R, it is important that the input voltage not exceed +21 V or drop below +3.3 V. In addition, the load should be able to withstand voltages up to +15 V. In order to ensure proper operation, the input voltage must be in compliance with the regulator\'s input voltage and current specifications.

The LD112PV12R adjustable Soft Start and Shutdown feature eliminates inrush current and provides precise control over voltage turn-on and turn-off time. Additionally, the regulator provides an adjustable slow start, wherein the output voltage begins ramping up from a lower voltage level and slowly climbs up to the needed regulated voltage. This prevents any potential problems caused by large inrush current when switching-on the power supply.

In addition to the adjustable Soft Start, the regulator also features temperature monitoring, temperature protection, and adjustable overvoltage protection. The temperature sensor allows for precise detection of temperature signals and the overvoltage protection feature adds an extra safety measure in an event of an unexpected power surge. When the output voltage reaches an unacceptable level, the regulator will shut down to protect the connected system. In a similar fashion, the temperature protection function limits the maximum temperature of the system, thus preventing any potential damage resulting from overheating.

The LD112PV12R offers a variety of features and performance parameters, providing excellent performance and protection in various applications. Its adjustable Soft Start and Shutdown, is particularly helpful when a supply must switch on and off quickly, while still providing an efficient power distribution network. The temperature monitoring and overvoltage protection functions help to protect the system against any potential damage due to a sudden surge of power.
