REF3233AMDBVREPG4

PMIC – Voltage Reference

The linear voltage regulator REF3233AMDBVREPG4 is a low-dropout voltage regulator used in systems that require accuracy, high system voltage range, and low-power operation. This voltage regulator comprises a buried zener diode and a complementary pair of NPN transistors. It offers the designer the ultimate combination of low noise (100 μVpp) and low quiescent current (120 μA) performance, in a small SOT-23 package.

The REF3233AMDBVREPG4 is mainly used in precision voltage reference applications. Its primary function is to generate a reference voltage of precisely 3.3 volts, which is required in some integrated circuit chips to obtain accurate electric parameters. It is useful in applications such as high accuracy analog-to-digital converters, active filters, and oscillators.

The REF3233AMDBVREPG4 has a typical drop-out voltage of less than 200 mV, which enables the device to deliver up to 200 mA of output current. This device also has a wide operating temperature range from -40°C to +125°C, which allows it to be used in a variety of extreme environments.

The voltage reference of the REF3233AMDBVREPG4 consists of two main components – a resistive-divider network and an internal zener diode. The resistive-divider network consists of two external resistors, R1 and R2, that set the reference voltage of the device. The internal zener diode stabilizes the reference voltage by limiting the reverse current that flows during transients or line faults.

In addition, the REF3233AMDBVREPG4 has excellent line and load regulation characteristics. Its line regulation is typically 0.2%, while its load regulation is typically 0.1%. These characteristics make the voltage regulator ideal for systems that require precision and accuracy.

The REF3233AMDBVREPG4 is a small and efficient device, providing linear regulation and accurate reference voltages. It is suitable for a wide range of applications, including precision voltage reference and current limiting. The device provides high accuracy and stability, as well as excellent line and load regulation characteristics.
