REF3225 Description

Short technical summary and product information.

The Texas Instruments REF3225 is a low drift, micropower, low-dropout, precision voltage reference family available in the SOT23-6 package. Its small size and low power consumption make it an excellent choice for portable and battery-powered applications.

 

Key electrical characteristics include a 2.5V output voltage with a maximum initial accuracy of 0.2%. The temperature coefficient is specified at a maximum of 7ppm/°C over 0°C to +125°C and 20ppm/°C over -40°C to +125°C. It offers a high output current capability of ±10mA and a low quiescent current of 100µA maximum.

 

The device operates from an input voltage range of 2.55V to 5.5V and features a low dropout voltage of 5mV. It is stable with any capacitive load and can be operated from a supply as low as 5mV above the output voltage under no load conditions.

 

The REF3225 is housed in a microsize SOT-23-6 package, suitable for surface mount applications. All models are specified for the wide operating temperature range from -40°C to +125°C.
