The REF3133AIDBZR from Texas Instruments is a fixed 3.3V series voltage reference IC designed for high-precision, low-power applications. It offers a maximum temperature coefficient of 20 ppm/°C across an operating temperature range of -40°C to +125°C, with a maximum initial accuracy of ±0.2%.
This voltage reference IC features a typical quiescent current of approximately 100 µA and can source or sink up to ±10 mA of load current. It is designed to maintain stability under any capacitive load without requiring an external load capacitor. The low drop-out characteristic allows regulation with a supply voltage only about 5mV above the output.
Packaged in an ultra-compact 3-pin SOT-23 (DBZ) package, the REF3133AIDBZR is well-suited for space-constrained designs. Its combination of precision, low power consumption, and small form factor makes it ideal for portable and battery-powered devices, ADCs/DACs, instrumentation, and communication systems requiring a stable reference voltage.
