Working Principle

The ADR5043BKSZ-REEL7 is based on a bandgap reference topology. It consists of two transistors operating in a complementary configuration. A reference voltage is created at the bases of each of the two transistors by using part of the voltage on the power source and a voltage reference from the bandgap circuit. The output voltage is created by combining the collector currents of the two transistors. The resulting reference voltage is stable over temperature and load conditions.

The device also features an active clamping circuit with an adjustable threshold which prevents the device from exceeding the power supply voltage. This ensures that the reference voltage remains stable despite any transient voltage changes. Additionally, there is an optional disable pin that can be used to shut the device down in order to save power consumption.
