VRE4141K

VRE4141K is a voltage reference IC composed of a bandgap reference and an associated circuit, offering a convenient, low-power reference and reference buffer amplifier, designed to provide a precise 16V power source for the analog and digital circuitry of portable electronic devices. It is part of the PMIC - Voltage Reference product family.

The VRE4141K can be used to ensure high accuracy and reliability in a wide range of applications, including amplifiers, DC to DC converters, voltage regulators, switched-mode power supplies, optical receiver circuitries, and high-voltage sensing.

The VRE4141K combines a low dropout bandgap regulator and an adjustable, low power reference voltage source, and produces a low noise, fixed precision output voltage of 16 volts. It offers high accuracy and fast response time, and is designed to minimize power consumption, minimize thermal stress due to temperature, and reduce the need for external components.

The VRE4141K offers an external voltage adjust pin to increase its output voltage to up to 22 V, and provides wide output stability over the full operating temperature range. The device also provides an enable/disable feature, allowing the user to put the outputs into a low-power, low-noise shutdown state. This makes the device suitable for applications requiring low power dissipation during quiescent periods.

The VRE4141K incorporates a wide range of protection features, such as reverse polarity protection and over-temperature protection, which ensure its reliability and long lifetime. The device also includes an active current limitation and thermal foldback protection, which allows the device to operate in harsh environments and reduce the risk of overheating. The thermal foldback feature also reduces power dissipation through the shutdown process.

The VRE4141K works by using a low dropout, bandgap voltage reference as the basis for its output voltage. The bandgap reference is a constant voltage source that is not affected by changes in voltage or temperature. The bandgap reference is then regulated by an adjustable voltage reference, which is adjusted by an external voltage to adjust the output voltage of the device. The device also uses a current source and a shunt resistor to adjust the output voltage. This allows the device to maintain the precise voltage output even under varying power conditions.

The VRE4141K is manufactured in a 5x5mm package, in a range of colors, and is RoHS compliant. It can be used in a wide range of applications, including networking, telecom, computing, and industrial equipment. It is also suitable for use in other applications that require a precise and constant output voltage.

In summary, VRE4141K is a voltage reference IC designed to provide a precise 16V power source for analog and digital circuits. It is part of the PMIC - Voltage Reference product family and is suitable for use in a range of applications, including amplifiers, DC to DC converters, voltage regulators, switched-mode power supplies, optical receiver circuitries, and high-voltage sensing. The device offers high accuracy and fast response time, and is designed to minimize power consumption, minimize thermal stress due to temperature, and reduce the need for external components.
