Voltage Reference (VR) devices are designed to provide precise output voltages that are independent of input voltage, temperature and loading. The LM4040DIM3X-2.5 is a programmable voltage reference that offers low temperature drift, low noise and excellent accuracy over temperature and time. This device is ideal for applications such as SMPS, DC-DC converters and Voltage Supervisory Circuits.

The LM4040DIM3X-2.5 is a three-terminal device. A voltage is applied to the reference terminal and the output is taken from the Vout terminal. The third terminal (Trim terminal), which is connected externally to a fixed voltage, provides the possibility of programming the reference voltage at the Vout terminal with an accuracy of ±2.5%. The intrinsic error of the LM4040DIM3X-2.5 is less than ±25mV over the entire operating temperature range. The temperature coefficient of the device is typically in the range of ±75ppm/°C.

The LM4040DIM3X-2.5 is available in two packages, the 8-pin SOIC-N and the 8-pin MSOP-N. Both packages are designed to offer a wide working range of -55°C to +125°C ambient temperature operation, making the device suitable for high temperature and harsh environment applications such as automotive and industrial control. The operating supply voltage range of the LM4040DIM3X-2.5 is 1.5V to 15V.

The LM4040DIM3X-2.5 is an ideal voltage reference for precision applications in portable and handheld electronic devices, such as cell phones, PDAs, digital cameras, MP3 players and gaming consoles. Due to its wide operating range and small form factor, it is also suited to automotive and industrial applications where space is limited and precision is required.

The LM4040DIM3X-2.5 enables designers to create designs with lower power requirements, less complexity, and improved accuracy due to its low noise and low temperature drift features. Furthermore, the wide temperature range and programmable trim feature allow the design of power supplies with better efficiency and higher accuracy than with the use of linear regulators.

In summary, the LM4040DIM3X-2.5 is an ideal voltage reference for applications requiring precision and low noise performance over a wide temperature range. Its three-terminal configuration and programmable trim feature make it an excellent choice for a wide variety of precision applications including SMPS, DC-DC converters and Voltage Supervisory Circuits.
