The LM4041CIDCKT is a low-power, shunt voltage reference designed for temperature stability and accuracy. This voltage reference offersa wide temperature operating range of -40°C to 125°C, with a low operating current of 0.3mA and a fast start-up time of 1.5 ms. It provides excellent stability in a wide range of dynamic voltage conditions. The LM4041CIDCKT is ideal for applications requiring low power and stable reference voltages, such asamplifiers, analog-to-digital converters, power supplies, motor control systems, LED lighting, and more.

The LM4041CIDCKT belongs to the group of PMIC (Power Management Integrated Circuits). Specifically, this voltage reference belongs to the Voltage Reference category. A voltage reference is an electronic device that outputs a fixed voltage regardless of changes in the input voltage or temperature. Voltage references are typically used in conjunction with other circuits to convert an input analog voltage into a digital output.

The working principle of the LM4041CIDCKT voltage reference is based on active components. These active components use the available power to maintain their own level of voltage stability. The voltage reference uses a shunt regulator circuit, consisting of a transistor and a resistor. The resistor-transistor combination acts as a voltage divider, with the transistor acting as the shunt element. This causes the output voltage to remain constant as the input voltage changes.

The LM4041CIDCKT also offers a programmable output voltage. The voltage range is programmable from 1.25V to 10.00V with a single resistor. The output voltage is adjusted by connecting a resistor between the ADJ and GND pins, and the resistor value is calculated using the following formula: Vout = 1.25V + (R x 0.100V).

In addition, the LM4041CIDCKT also offers overvoltage protection. The overvoltage protection circuit monitors the output voltage for any overvoltage conditions. If an overvoltage condition is detected, the overvoltage protection circuit will shut down the IC to prevent damage.

The LM4041CIDCKT is a low-power, highly stable voltage reference that is ideal for a variety of applications requiring low power and precise voltage regulation. It is programmable, offersovervoltage protection, and is available in a small SOT-23 package.
