PMIC - Voltage Reference

The LM4041EIM3X-1.2/NOPB voltage regulator is a stable, one-time programmable and accurate source of reference current. It offers excellent accuracy and power performance. This precision voltage reference is intended to serve in a wide range of applications, which include analog-to-digital converters, current measuring devices, linear and switching regulation, temperature measurement and control, and many other applications requiring accurate input signal conditioning.

The LM4041EIM3X-1.2/NOPB voltage reference is designed to provide a regulated, 1.2V technology independent, output voltage. It uses an external resistor to set the reference current (IREF) or the output voltage (VREF) to a specific value. The resistor can be a carbon composition or a metal film. The circuit has built-in hysteresis which prevents it from oscillating during any load fluctuations.

The LM4041EIM3X-1.2/NOPB can be easily configured for the desired output voltage. The external resistor can be adjusted for the desired current (IREF) or to obtain the desired output voltage (VREF). The reference voltage is sourced from the regulated output and it has very low temperature coefficient, which means that it is better at maintaining a more precise voltage over a wide temperature range than a resistor.

The LM4041EIM3X-1.2/NOPB is fabricated using state-of-the-art CMOS technology. It features very low power dissipation, excellent temperature stability over the entire operating temperature range, and very high reliability. It also features a 4-wire serial interface that can be used to program the reference voltage with a clock or data stream. This makes the unit particularly suitable for remote or distributed applications.

The LM4041EIM3X-1.2/NOPB also features internal current limiting and thermal protection circuitry. These features make it ideal for applications in harsh environmental conditions, such as automotive and industrial. The circuit can operate from a wide range of power supply voltages, from 3V to 15V.

In summary, the LM4041EIM3X-1.2/NOPB is a very efficient and reliable voltage reference for a wide range of applications. It has low power consumption and is able to maintain a very stable output voltage over a wide temperature range. It is ideal for analog to digital conversion and switching regulation. The built in hysteresis prevents it from oscillating and the external resistor to set the reference current or output voltage ensures that it is accurately set to the desired value.
