Voltage references, also known as reference sources or reference voltages, are a key component in controlled-voltage power supplies, voltage measurement systems, and other precision circuits. A voltage reference, sometimes known as a voltage regulator, is a regulated source of a controlled amount of voltage. REF01CESA+ is a low-power, SOT-23-packaged, precision bandgap voltage reference that is ideal for use in battery-powered and other demanding designs. This article provides an overview of the REF01CESA+ application field and working principle.

Application Field of REF01CESA+
The REF01CESA+ is specifically designed for use in ADC and DAC systems. It can be used as a reference source for single supply systems or dual supply systems. With its low power consumption, it is particularly well suited for portable applications and applications where power consumption is critical. It is also suitable for automotive and industrial applications, as well as many general-purpose applications. It has an operating temperature range from -40°C to +125°C.

Working Principle of REF01CESA+
The REF01CESA+ is a precision bandgap voltage reference, which means it utilizes a bandgap reference voltage as a reference voltage for an electronic circuit. It works by creating two different voltage references: a negative and a positive supply. The negative and positive references are used to establish a range of voltages in between which the output is maintained. The output is then compared to the reference voltage, and the amplifier\'s output is adjusted accordingly to maintain a constant output voltage, even if the input voltage varies. The REF01CESA+ also has low-power consumption, which is beneficial if the output voltage needs to be maintained during low-power or standby modes.

The REF01CESA+ is a single-supply, low-power precision bandgap voltage reference ideal for portable applications that require high accuracy, while consuming minimal power. It provides an output voltage of 2.5 V to 5 V and is also suitable for use in various single supply systems. The REF01CESA+\'s precise voltage output, low-power consumption, and small package size make it an optimal solution for a variety of system designs where precision voltage reference is essential.
