Working Principle

The MAX8860EUA28+T combination consists of a precision voltage reference and a low-dropout (LDO) linear regulator.

The voltage reference circuit is composed of a bandgap circuit, an adjustable 6-decade resistor ladder and a low temperature coefficient (TC) current sink. This circuit acts as an adjustable current source and supplies a reference voltage to the non-inverting terminal of the LDO regulator.

The LDO regulator is composed of an amplifying stage, a pass-transistor, current sources and output buffers. The regulator compares the output voltage to the voltage reference and adjusts the pass-transistor’s gate voltage so that the output voltage is maintained at the desired value.

Moreover, the MAX8860EUA28+T has a wide range of integrated protection features, such as reverse bias protection, thermal protection and overcurrent protection, which ensure the safety of the circuit and the reliability of the application.
