Voltage references are electronic circuits that generate a fixed reference voltage level regardless of the current that passes through it. The MCU1501T-18E/SN is a voltage reference integrated circuit that is typically used in power management and audio applications. It is a low-cost, low-noise, low-dropout (LDO) voltage reference with an operating temperature range of -40 to 85°C and a supply current draw of only 1 μA. The device is available in both through-hole and surface-mount packages.

The MCU1501T-18E/SN voltage reference is used in a variety of applications, from power management and audio, to automotive, industrial and instrumentation. It provides a regulated output voltage of +18V and is designed for use with low-power microcontrollers. The device employs a two-terminal voltage regulator (Vreg) to provide a stable reference voltage to the microcontroller. The Vreg feature ensures that the output voltage is accurate and constant, even under varying input and load conditions.

The MCU1501T-18E/SN voltage reference combines a simple and reliable structure with low cost and power dissipation. The device\'s output voltage is adjustable by an external voltage divider that can be set within the range of 12.75 to 18V. The output can also be monitored by an on-chip comparator. Additionally, the device features an integrated reverse-blocking Schottky diode that eliminates any potential backfeed issues. This ensures that the output is protected from possible overvoltage and reverse polarity conditions.

At the heart of the MCU1501T-18E/SN voltage reference is a band-gap reference circuit. This circuitry produces a precise reference voltage by utilizing two different currents that flow through two identical transistors. The two transistors are held at the same temperature and have the same current flowing through them. Since the two currents are equal, the difference in the voltages produced by the two transistors serves as the precise reference voltage.

The MCU1501T-18E/SN voltage reference combines an internal voltage reference, low noise, low power consumption, and wide temperature range, making it ideal for a variety of power management and audio applications. Its simple two-terminal connection, adjustable output voltage, easy setup, and reliable operation make this voltage reference the perfect choice for all your power management and audio application needs.
