PMIC (Power Management Integrated Circuit) is a comprehensive circuit for controlling and regulating the power of an electronic system. The Voltage Reference comprises of a set of circuits that are employed to provide a stable and accurate reference voltage for other circuits and components. Voltage references provide a stable, adjustable, and temperature stable voltage reference that sets the reference voltage for a particular operator or circuit. Among such voltage references, MCP1501T-33E/CHY is a 3.3V fixed output voltage reference IC with low temperature coefficient, suitable for a wide range of Power management applications.

MCP1501T-33E/CHY features a combination of low-voltage operation, low power consumption, high accuracy, and low temperature coefficient in a very small package. It is a three-terminal reference voltage device capable of providing a stable voltage output over a wide range of operating conditions and environmental conditions. The device is enclosed in a tiny MSOP package of just 0.75mm×2.8mm and uses a temperature compensation technique to reduce temperature sensitivity, making it useful for a variety of applications.

The device can be operated from a supply voltage of 2.7V to 5.5V. Its output voltage is 3.3V ±2% over the entire temperature range of -40°C to +85°C. Its low temperature coefficient ensures that its output voltage is stable even under temperature changes. Furthermore, the device has an internal input shunt regulation feature which eliminates the need for an external shunt resistor to regulate the input voltage. In addition, its low current consumption (330 μA) makes it suitable for battery-operated applications.
