Power Management Integrated Circuit (PMIC) devices are essential components for enabling a wide range of products and technologies. PMIC devices are typically implemented to regulate the voltage, current and temperature of electronic circuits and devices. As such, PMICs play an essential role in the stable and reliable operation of most modern electronic products. The LM4050CEM3X-10/NOPB is a PMIC device that falls into the category of Voltage References, meaning that it is designed to provide a stable voltage output, irrespective of variations in input voltage, temperature or load.

The LM4050CEM3X-10/NOPB is an External Voltage Reference that is offered in a three-terminal SOT-23 package. It provides an accurate, low-power, low-noise, low drop-out voltage reference. The device can be used for a variety of applications, including the setting of the output voltage in other regulators, precision timing reference for crystal oscillators, DACs and ADC reference source and bandwidth control in op-amps. It is also suitable for applications requiring a regulated voltage source such as temperature compensation of Wheatstone bridges, temperature sensors, pressure transducers and low voltage DC errors.

The LM4050CEM3X-10/NOPB is a bandgap-based reference device, meaning that its output voltage is derived from the bandgap voltage of silicon. The major elements of the bandgap circuit are the matched transistors, one functioning as a variable emitter resistor, the other used as the collector load. As temperature changes, the emitter resistor tends to keep its value relatively constant, while the collector load increases or decreases in proportion to the temperature. This causes a change in the output voltage. To compensate for the change in output voltage, the reference circuit is designed with a negative temperature coefficient of resistance, which compensates for the positive temperature coefficient of the bandgap voltage.

The output voltage provided by the LM4050CEM3X-10/NOPB is fixed and does not change as the temperature or load changes. The device also exhibits excellent temperature stability down to -40°C, with a temperature coefficient of 0.2mV/°C. It also exhibits an excellent load regulation of 0.5mV/mA, with an extremely low dropout voltage of 0.5V. The output voltage range available is 1.5V to 9.0V, with a maximum output current of 20mA. The device supports a power-down mode, with a quiescent current of only 100µA. Finally, its I/O platform supports a wide operating voltage range, from 3V to 14V.

In conclusion, the LM4050CEM3X-10/NOPB is an excellent voltage reference device, suitable for a wide range of applications, from setting the output voltage of other regulators to providing precision timing reference for crystal oscillators. It offers excellent temperature stability and load regulation along with low dropout voltage and a power-down mode. As such, it can be a great choice for any power management design project.
