LM4041D12ILP

The LM4041D12ILP application field and working principle, or LM4041D12ILP for short, is a low-cost precision voltage reference. It is part of the Power Management Integrated Circuit (PMIC) family, specifically the Voltage Reference. A Voltage Reference, or simply a Reference, is a device used to provide an accurately known reference or established reference voltage. A reference is an important tool in the field of analog circuit design, as it acts as a base or foundation to accurately define voltages used in circuits. It helps ensure accuracy and consistency in devices that measure, regulate and maintain voltage levels.The LM4041D12ILP is a band-gap voltage reference, meaning that it uses the avoided crossings of two bandgap materials to create a well-adjusted output voltage. Its low cost and high precision makes it suitable for a wide range of applications, such as in low power devices, precision instruments, digital and analog circuits, voltage regulators, and more. The LM4041D12ILP has a wide operating temperature range from -40°C to +150°C that is suitable for applications or environments that need a reference voltage to be reliable in variable temperatures and temperatures extremes. It can also operate with a 2 V to 18 V input range, which means that it is suitable for various design requirements. The LM4041D12ILP also has a low output voltage noise of 180 µVrms, which makes it suitable for noise-sensitive applications, like in medical instruments. Moreover, it has high stability of 157 µV/V, which means that it can withstand changes in the output voltage even with changes in the environmental conditions, such as temperature and supply voltage.In addition to its low-cost and versatility, the LM4041D12ILP has a typical output voltage of 1.24 V and a small size of a 5-pin SOT-23 package. The small size makes it well-suited for portable applications, such as in smart phones and calculators where space and weight is a priority. In summary, the LM4041D12ILP is an excellent voltage reference for designers that need precision, high stability and low-cost in their designs. With its wide operating temperature range, low output voltage noise and small size, it is perfect for a variety of applications, such as in instruments, low-power devices and voltage regulators.
