Modern power management has become a key factor in the development of a wide range of applications. Power management integrated circuits (PMICs) are extremely useful in maintaining power supplies with as little as possible risk of failure and maximum performance level. One of the operating devices capable of meeting the power management needs is the LM285MX/NOPB, a part of the Voltage Reference family of PMICs offered by Texas Instruments. This voltage reference operates over an ambient temperature range of -40 to 125 °C and provides a precise reference voltage with minimal noise.

The LM285MX/NOPB is designed to generate a single reference voltage output of 1.235 V with a temperature stability of ±0.1%. The output voltage can be adjusted to values up to 2.04 V with the addendum of external resistors. It operates either by self-heating or by an external Heater implementation. This voltage reference is capable of self-trimming and can also be externally trimmed to higher accuracy during production. It also features a high output impedance undisturbed by load or line transients. This high output impedance is useful for applications that require high accuracy and low power.

The LM285MX/NOPB provides 2 to 3 mV/°C of temperature-independency and uses a negative supply voltage for its operation. Its low noise performance (35 µVrms) makes it suitable for low noise applications such as data converters, references for digital-analog converters (DACs) and microcontroller (MCU) references.

The LM285MX/NOPB provides a wide range of protection features that prevent it from damage due to overvoltage, overtemperature and overtemperature cycling. It also features current limit protection, diagnostics output, and internal fault detection. These features ensure that the device can be used safely in sensitive circuitry.

The LM285MX/NOPB is used in a wide range of applications, from general purpose to automotive use. It is used in multiplexers, current measurement, converters and driver circuits, as well as any application requiring a precise reference voltage. It is also used in automotive measurements, medical equipment, and even in complex industrial processes.

In conclusion, the LM285MX/NOPB voltage reference is an ideal choice for applications requiring precise reference voltages, with low power consumption, high output impedance and robust protection features. It is capable of providing reliable reference voltages in the most demanding conditions, and its wide range of applications make it an indispensable part of any power management system.
