Description and Introduction

15ppm/C Max/ 100UA/ SOT23-3 SERIES VOLTAGE REFERENCE **Precision Power Management with the REF3133AIDBZR Voltage Reference**  

In today’s demanding electronic designs, accuracy and stability are non-negotiable. The REF3133AIDBZR from Texas Instruments is a high-performance, low-dropout voltage reference that delivers exceptional precision for critical applications. With a fixed output of 3.3V and ultra-low temperature drift, this component ensures reliable performance in industrial, automotive, and medical systems where consistency is paramount.  

Engineered for excellence, the REF3133AIDBZR features an initial accuracy of ±0.2% and a low temperature coefficient of 50ppm/°C, minimizing output variations across operating conditions. Its low dropout voltage of 200mV enhances efficiency, making it ideal for battery-powered and energy-sensitive designs. Additionally, the device supports a wide input voltage range of up to 18V, providing flexibility in diverse power supply configurations.  

The REF3133AIDBZR excels in noise-sensitive environments with a low output noise of 65µVpp (0.1Hz to 10Hz), ensuring clean and stable voltage references for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and sensor interfaces. Its robust design includes reverse current protection and a low quiescent current of 100µA, further optimizing system reliability and longevity.  

Available in a compact SOT-23 package, this voltage reference is designed for space-constrained applications without compromising performance. Whether used in precision instrumentation, power management circuits, or embedded systems, the REF3133AIDBZR delivers the accuracy and stability needed for mission-critical operations.  

For engineers seeking a dependable voltage reference solution, the REF3133AIDBZR stands out as a high-performance choice, combining precision, efficiency, and durability in a single compact package.

Application Scenarios & Design Considerations

15ppm/C Max/ 100UA/ SOT23-3 SERIES VOLTAGE REFERENCE

Alternative Part Number

  • ADR4533ARZ --: 3.3V series voltage reference with similar initial accuracy and low drift, pin-compatible function in SOT-23 style packages, well-established alternative to the REF3133.
  • MAX6033AAUT33 --: 3.3V precision series reference with low dropout and low noise, suitable drop-in functional replacement for 3.3V reference applications.
  • LM4132AMF-3.3 --: 3.3V series voltage reference from TI with comparable accuracy and low quiescent current, same manufacturer family but different series naming for easy distinction.
