Working Principle

The ADR293TRUZ-EP works on the principle of using a bandgap reference as a stable voltage source. The device uses a voltage reference circuit that contains two transistors to provide a stable reference voltage, which can then be used to set the output voltage of the device. The voltage reference circuit includes two transistors – a p-channel MOSFET and an n-channel MOSFET. The p-channel MOSFET is used to provide the positive voltage reference and the n-channel MOSFET is used to provide the negative reference. The transistors are connected in series between two protective diodes. When the device is powered on, the transistors are driven with an accurate voltage reference generated internally by ADR293TRUZ-EP. This reference voltage is then compared with an adjustable external reference voltage to produce an error voltage. The error voltage is then used to adjust the output voltage of the device and maintain a stable voltage reference.

Application Field

The ADR293TRUZ-EP is suitable for use in a variety of applications. Due to its wide output voltage range, high accuracy and low noise, it can be used in microprocessor-controlled systems, audio and video systems, and other applications like automotive, industrial equipment, telephones, and digital cameras. Moreover, its low power consumption and wide temperature range make it ideal for use in wearable and portable electronics, communication systems, and automotive systems. Additionally, it is small in size and can be used in space-constrained applications, such as mobile phones, industrial machines, and embedded systems. The device is also suitable for use in low-voltage battery-powered systems such as smart watches, internet of things (IoT) devices, and other low-power applications.
