PMIC (Power Management Integrated Circuit) is an important component used in embedded systems, providing a range of power supply options through a single package. The LM4140CCM-2.0 is a common PMIC in the voltage reference category.

In today\'s competitive consumer electronic products, increasing battery life is a critical factor that cannot be ignored. It is essential to maintain the stability of the power supply output, especially when the input voltage changes over time. As such, a voltage reference is important to regulate the output voltage of the power management circuit. The LM4140CCM-2.0 is a positive voltage reference with a temperature coefficient of typically 0.002%.

This voltage reference delivers an accurate and stable output voltage relative to its input voltage, even when the input voltage is subject to fluctuations. It also has a wide operating temperature range of -40°C+125°C. Due to its low noise and low temperature coefficient, it is ideal for applications where long-term stability and accuracy are critical.

Such applications include mobile computing, audio and video, automotive, low power systems, and embedded systems. In mobile computing and automotive, the LM4140CCM-2.0 can be used to provide precise and stable output voltages. The low power system can also benefit from the low operating current of this voltage reference.

The LM4140CCM-2.0 also provides an over-temperature protection (OTP) circuit via an overtemperature detection pin that senses the die temperature of the voltage reference. When the voltage reference becomes too hot, the OTP circuit will automatically shut down the voltage reference to protect it from damage.

The LM4140CCM-2.0 also has an edge rate control (ERC) circuit which can adjust the reference voltage output by changing the edge rate. This enables the user to optimize the reference voltage output for different applications.

In summary, the LM4140CCM-2.0 voltage reference is an ideal choice for applications that require accurate and stable output voltage with low power. Its wide operating temperature range and built-in OTP and ERC circuits make it highly reliable and flexible for different applications.
