It is available in 20-pin SOT-23 (small outline transistor—23) packages, and has low current consumption, making it ideal for applications that require minimal power consumption.

Application Field

The NCP694DADJHT1G is a versatile shunt regulator that can be used in a wide range of applications where a precise and low output noise voltage is required. Its low current consumption allows it to be used in battery powered applications, while its wide input voltage range makes it suitable for use with a variety of power sources. The most common applications for the NCP694DADJHT1G are medical instruments, data logging, and test and measurement equipment. Its low output noise makes it ideal for use in devices that require precise voltage measurements. It can also be used to provide a regulated DC power supply for other components in the circuit.

Working Principle

The NCP694DADJHT1G is a positive shunt regulator, and employs a zener diode to limit the output voltage. The zener diode is connected between the output and ground, and allows only a predetermined voltage to be output to the load. The voltage is regulated by the amplifier and feedback resistor connected to the output terminal. The output voltage is determined by the voltage drop across the zener diode, and is controlled by a feedback adjusting circuit. An adjustable resistance (trim resistor) is connected to the feedback terminal, and is used to adjust the output voltage to the desired level. The amplifier in the circuit ensures that the output voltage remains stable regardless of variations in the input voltage or load current.

Conclusion

The NCP694DADJHT1G is a low noise shunt regulator with an adjustable output voltage of up to 32V. It is suitable for a range of applications where precision voltage regulation and low power consumption are required, such as medical devices, data logging and test and measurement equipment. The voltage is regulated by a zener diode connected to a feedback circuit, and is adjusted with an adjustable resistance connected to the feedback terminal.
