REF2933AIDBZR Description

Short technical summary and product information.

The REF2933AIDBZR from Texas Instruments is a precision, low-power, low-voltage dropout voltage reference family available in a tiny 3-pin SOT-23 package. This device provides a stable 3.3V output voltage with a maximum temperature coefficient of 100 ppm/°C and an initial accuracy of 2%.

 

Designed for efficiency, the REF2933AIDBZR operates with a low quiescent current, typically 0.042mA, and a maximum of 50µA. It can supply an output current of up to 25mA. The device has a low dropout voltage of 1mV, allowing it to operate effectively even with input voltages close to the output voltage.

 

The operating temperature range for the REF2933AIDBZR is -40°C to 125°C, ensuring reliable performance in demanding environments. It is housed in a compact SOT-23 package, measuring approximately 6.9204 mm², making it ideal for space-constrained portable and battery-powered applications. The REF29xx series does not require a load capacitor and is stable with any capacitive load.
