REF3133AIDBZR | TI 3.3V High-Precision Voltage Reference | 20 ppm/°C | Low Power

Product Overview

     The REF3133AIDBZR is a series-voltage reference IC from TI with a fixed 3.3 V output, packaged in a compact 3-pin SOT-23 (DBZ) package. It features typical quiescent current around 100 µA and a maximum temperature coefficient of 20 ppm/°C across –40 °C to +125 °C.

     This device is ideal for applications demanding high precision voltage reference, low power consumption, and small form factor—such as portable devices, battery-powered systems, and analog front-ends. The REF31xx family does not require an external load capacitor and maintains stability under any capacitive load, while being able to source or sink up to ±10 mA load current.

Key Features

• Output voltage: fixed 3.3 V.
• Temperature coefficient (max): 20 ppm/°C over –40 °C to +125 °C.
• Initial accuracy (max): ±0.2%.
• Typical quiescent current: ~100 µA.
• Can source or sink up to ±10 mA load current.
• Low drop-out: able to regulate with supply only ~5 mV above output.
• Package: 3-pin SOT-23 (DBZ) ultra-compact.
• Operating temperature range: –40 °C to +125 °C.

Applications

• Precision voltage reference in battery-powered systems and portable devices.
• Reference source for ADCs (analog-to-digital converters) and DACs (digital-to-analog converters).
• Portable medical equipment, instrumentation, and power management modules.
• Communication devices, sensor interfaces, and data acquisition systems.
• Industrial control modules and embedded systems requiring high-precision reference voltage.
