LM236DE4-2-5 is a programmable voltage reference device in the PMIC - Voltage Reference category. It is specially designed for use in PLC (programmable logic controllers) and industrial automation systems. It provides up to 4 independent outputs for the voltage adjustment of different analog components of the system, such as sensors, LED drivers and power switching devices. In addition, its features make it suitable for use in a variety of industrial applications.

The LM236DE4-2-5 device consists of four independent precision voltage reference circuits, each with different output voltage accuracy and temperature coefficient. The four outputs provide adjustable references ranging from +2.5V to +10V. Each reference output can be adjusted individually. The device has a temperature coefficient of 0.01%/C, making it suitable for temperature-sensitive applications. The device also has an input offset voltage of 5mV, and a maximum operating temperature range of +85C.

The LM236DE4-2-5 has two modes of operation — static mode and dynamic mode. In static mode, the device outputs are fixed to predetermined voltages. In dynamic mode, the device adjusts the output voltages to maintain a specific output voltage. For example, the device can be used to adjust the voltage of a LED depending on the ambient light intensity. This allows the LED to maintain a uniform brightness even in fluctuating light conditions.

The LM236DE4-2-5 also includes an adjustable current limit feature. This feature prevents current overload and reduces the risk of catastrophic damage to the device. The current limit of each output can be individually adjusted. Furthermore, the device includes overvoltage and undervoltage protection, thermal overload protection, and overload protection. These features ensure the safe and reliable operation of the device in the toughest of conditions.

In addition to these features, the LM236DE4-2-5 also includes low-power start-up mode and sleep mode. The low-power start-up mode reduces the start-up current and increases the duty cycle of the device. This increases the overall power efficiency of the device. The sleep mode conserves power by putting the device in a low power state when not in use.

Overall, the LM236DE4-2-5 is an ideal choice for applications that require precision regulation and robust performance. Its features make it suitable for industrial-grade applications, and its flexibility makes it easy to integrate into existing systems. The device also provides excellent protection, reliability, and power efficiency. Finally, its wide range of adjustable reference voltages and adjustable current-limit output make it a versatile and reliable choice for various demanding applications.
