ADR423ARMZ is a low-input voltage, low-drop-out, fully-featured, positive voltage reference intended for use in voltage references and regulators, rheostats, programmable references, conditioners and stabilizers, and other battery-powered applications.In single-cell power supply applications, the ADR423ARMZ supplies up to 2.5 mA of output current while maintaining a precise output voltage. The dropout voltage of the device is nominally 160 mV at 1 mA of output current. The device is supplied in a SOT23-6 package, allowing it to be used in a variety of applications.The ADR423ARMZ consists of three main components: an input capacitor, an output capacitor, and a voltage reference circuit. The input capacitor is used to reduce the input voltage ripple before it reaches the voltage reference circuit. The output capacitor acts as a filter, providing a smooth output voltage signal.The voltage reference circuit consists of an adjustable bandgap reference and an amplifier. The bandgap reference sets the output voltage, and the amplifier buffers the signal from the reference and provides the desired output current. When fully integrated, the device provides very low-dropout performance, and the output voltage is essentially independent of input voltage over an input voltage range of 1.8 to 6.0 V.The ADR423ARMZ is an ideal choice for applications that need a precise, efficient voltage reference with very low dropout and high output current. The device is perfect for use in battery-powered and other low-voltage applications like portable medical devices, communication systems, smart phones, and battery-powered industrial systems.The ADR423ARMZ has several advantages over other voltage references. These include low-input ripple, exceptional dropout performance, and low quiescent current. The device is easy to integrate into existing designs and offer multiple protection features to guarantee device protection. These protection features include input undervoltage lockout, output current limiting, thermal shutdown and short circuit protection.The ADR423ARMZ provides a great combination of low-dropout performance and exceptional temperature stability, making it a great fit for a variety of applications, including those in critical applications such as conditioners and stabilizers, programmable references, and battery-powered devices. Moreover, the ADR423ARMZ is fast to recover from a dropout condition, allowing it to be used in applications requiring fast power recovery.Overall, the ADR423ARMZ is an excellent, cost-effective choice for applications requiring a robust, low-dropout voltage reference. The device provides exceptional stability, low-input ripple, exceptional temperature characteristics, and robust protection features, making it an ideal choice for applications such as portable medical devices, industrial systems, and communication systems.
