Power management integrated circuits (PMICs), also referred to as voltage references, are electron devices which provide a stable and reliable output voltage in order to control the power and current in any given system. The LM285D-2.5R2G is a precision voltage reference produced by Texas Instruments which offers superior performance and accuracy in comparison with other reference devices.

This voltage reference is designed to operate with an output voltage of 2.5V and a wide range of temperature conditions and offers an input voltage stability of 0.3mV (rms) over the specified range of -40 to +125 °C. The LM285D-2.5R2G is composed of a precision precision temperature compensated voltage reference along with a current output buffer stage that ensures an accurate and precise output voltage. In addition, the device is designed to dissipate very low, stable, concentrated and precise currents of 3mA in order to maintain a stable output voltage with a current output accuracy of 0.008 mA. The LM285D-2.5R2G also has a low temperature coefficient of 0.2ppm/°C, which ensures that the output voltage remains accurate over a wide range of temperature conditions.

The LM285D-2.5R2G is commonly used in applications that require a stable voltage reference such as digital to Analog converters (DACs), portable battery powered equipment, telecommunications, and metrology equipment. In addition, the device is suitable for use in portable medical devices and closed-loop control applications. The device is also used in multiple applications that require a high degree of accuracy and tight regulation such as system power supply and systems that require precision performance.

The working principle of the LM285D-2.5R2G involves two stages, the voltage reference stage and the output stage. The voltage reference stage is designed to provide a stable and accurate output voltage of 2.5V regardless of changes in temperature or input voltage. The design is based on a bandgap circuit which acts to stabilize the output voltage. The output stage is designed to buffer the voltage reference stage and maintain the output voltage by dissipating a regulated current of 3mA.

The LM285D-2.5R2G provides superior performance and accuracy in power supply and control applications. Its wide temperature range and low current dissipations make it an ideal solution for a range of digital and communication applications. It is also suitable for use in metrology equipment, closed-loop control systems, and systems that require precision performance.
