PMICs (Power Management ICs) are integrated circuits that are designed to enable better energy efficiency in systems. They enable systems to intelligently allocate energy, reduce idle energy consumption and extend the longevity of battery powered products. Voltage references, a component within a PMIC, are essential to maintain system accuracy and stability in converting fixed voltages as well as a range of alternating current and voltage values for various applications.

KA431ZTF is a low output voltage temperature compensated Zener reference, commonly used in PMICs. The device provides an output voltage tolerance of ±2.0%, which is the highest available in industrial temperature range. Furthermore, it offers low drift over the full industrial temperature range and low noise characteristics. The output voltage can be adjusted using external resistors, allowing for applications with different voltage set points. The device offers a temperature coefficient of 0.03%/°C to compensate for the effects of temperature changes.

The KA431ZTF provides a regulated output voltage below the input voltage with low noise, making it suitable for use in a variety of applications such as stabilized power supplies, battery powered devices, mobile devices and computers, among others. The ability to regulate both small and large output current requirements makes this device an ideal voltage reference for a wide range of PMICs. Specifically, due to its low output voltage tolerance and temperature drift, the KA431ZTF is best used in general-purpose applications that require a high degree of accuracy, such as microcontrollers, temperature controllers, and DSPs.

The working principle of the KA431ZTF is that its internal circuitry produces a regulated voltage using an internal Zener diode in a voltage divider configuration. The device allows for a wide input voltage range, from 10V to 40V, resulting in a lower dropout voltage. The output voltage is then set by connecting a resistor across the device’s reference voltage pins. The resistor sets the output voltage by dividing the input voltage. The temperature compensation of the device allows it to effectively adjust its output voltage in order to compensate for temperature variations, thereby ensuring that the output voltage remains stable and accurate.

In summary, the KA431ZTF is a low output voltage temperature compensated Zener reference suited for use in a variety of applications. It offers a temperature coefficient of 0.03%/°C and an input voltage range of 10V to 40V, allowing for a lower dropout voltage. Furthermore, the output voltage can be adjusted using external resistors, enabling applications with different voltage set points. The device’s internal circuitry produces a regulated voltage via a voltage divider configuration, which is then temperature compensated to ensure accuracy and stability. As such, the KA431ZTF is ideal for applications that require a high degree of accuracy, such as microcontrollers, temperature controllers, and DSPs.
