REF2033 Description

Short technical summary and product information.

The Texas Instruments REF2033 is a series voltage reference designed for applications requiring precise voltage regulation. It features two outputs, VREF and VREF/2, which are convenient for single-supply systems. The device boasts excellent temperature drift performance with a maximum of 8 ppm/°C over the -40°C to 125°C operating range and high initial accuracy of ±0.05% maximum.

 

With a low dropout voltage of 10 mV and a high output current capability of ±20 mA, the REF2033 is suitable for various power management tasks. It operates from an input voltage range of 3.32V to 5.5V and consumes a low quiescent current of 360 µA typical. The device also offers low frequency noise of 39.6 µVPP at 0.1 to 10 Hz.

 

Packaged in a microsize SOT-23-5 surface-mount package, the REF2033 is ideal for space-constrained designs. Its features make it well-suited for signal chain conditioning, current sensing, and overvoltage detection applications.
