The MAX6145ESA is a voltage reference designed by Maxim Integrated Products and is classified as a PMIC (Power Management IC). It is an adjustable, low-dropout voltage reference that consists of a precision bandgap voltage reference, an adjustable output amplifier, and a PNP pass transistor. The MAX6145ESA can operate at intermediate voltages to bias the bandgap accurately and maintain long-term reference accuracy. The MAX6145ESA is available in a SOIC-8 package.

The application field of the MAX6145ESA includes analog-to-digital converter (ADC) and digital-to-analog converters (DAC) circuitry. It can also be used in voltage related applications such as audio/video amplifiers, power supplies, power regulators, programming power supplies, and more.

The working principle of the MAX6145ESA is quite simple. Two transistors are connected in an unloaded circuit. A bandgap voltage reference generates a very precise reference voltage at the input point of the circuit. An output amplifier amplifies the voltage and feeds it to the output point of the circuit. The output amplifier is able to adjust the output voltage as it has a high gain. The MAX6145ESA has a PNP Pass transistor that is used to control the current drawn from the output. By regulating the current, the output voltage is regulated. This design ensures that no external dissipative components such as resistors or capacitors are required to regulate the output voltage.

In summary, the MAX6145ESA is a PMIC (Power Management IC) that is classified as a Voltage Reference. It is an adjustable, low-dropout voltage reference that consists of a precision bandgap voltage reference, an adjustable output amplifier, and a PNP pass transistor. Applications of the MAX6145ESA include analog-to-digital converter (ADC) and digital-to-analog converters (DAC) circuitry. The working principle of the MAX6145ESA is quite simple - two transistors are connected in an unloaded circuit, a bandgap voltage reference generates a very precise reference voltage at the input point which is amplified and fed to the output with the help of an output amplifier and a PNP Pass Transistor.
