A voltage reference is a type of electronic circuit designed to maintain a constant voltage across its outputs despite external circuit variations. This type of device is useful for measuring, setting and maintaining accurate voltage levels in a wide range of applications where voltage accuracy is essential. The ZR40401F50TC voltage reference from ZiLog is specifically designed to provide a 15V regulated output. This device is ideal for use in battery powered systems where a supply voltage of 15V is needed, as the typical quiescent current of only 100μA allows the use of small batteries, thereby increasing the overall capacity. The output voltage is also nearly independent of line and load variations over a wide temperature range.

The ZR40401F50TC utilizes a band-gap voltage reference circuit as its core, which ensures a constant output voltage regardless of the supply voltage or temperature. A precision transistor is used to match the output voltage, providing a stable and linear output. This circuit is then connected to an adjustable voltage divider, allowing the output voltage to be externally adjusted if desired. This adjustable voltage divider can be used to trim the output voltage to within ±2.5%.

The ZR40401F50TC has a variety of applications where a precise output voltage is required. It is ideal for use in battery powered systems such as monitoring and control applications, automotive electronics and portable audio equipment. It is also ideal for powering analog ads and controllers, as well as a reliable voltage reference in data converters and converter systems. The device is well suited to both commercial and industrial applications, as it is available in either an industrial or automotive grade package, providing the user with a wide range of options for their specific requirements.

The working principle of the ZR40401F50TC voltage reference is quite simple. Its band-gap reference circuit creates a voltage which is independent of temperature, line and load variations. This voltage is then electronically compared to an adjustable reference voltage set by the internal voltage divider; as the two voltaes are equal, a constant output voltage is generated. This output is then protected using a precision transistor which prevents it from overshooting or undershooting.

The ZR40401F50TC voltage reference is a reliable and precise device providing a stable and linear output in a wide variety of applications. The device is thermally stable, with a quiescent current of only 100μA, making it ideal for battery powered systems, as well as industrial and automotive applications. It is also temperature, line and load independent, making it the ideal choice in many applications.
