SBVS046A – DECEMBER 2003 – REVISED JANUARY 2004

15ppm/°C Max, 100µA, SOT23-3

SERIES VOLTAGE REFERENCE

FEATURES

DESCRIPTION

The REF31xx is a family of precision, low power, low dropout,

series voltage references available in the tiny SOT23-3 pack-

age.

● MicroSIZE PACKAGE: SOT23-3

● LOW DROPOUT: 5mV

● HIGH OUTPUT CURRENT: ±10mA

● HIGH ACCURACY: 0.2% max

● LOW I_Q: 115µA max

The REF31xx’s small size and low power consumption

(100µA typ) make it ideal for portable and battery-powered

applications. The REF31xx does not require a load capacitor,

but is stable with any capacitive load and can sink/source up

to 10mA of output current.

●

EXCELLENT SPECIFIED DRIFT PERFORMANCE:

15ppm/°C (max) from 0°C to +70°C

20ppm/°C (max) from –40°C to +125°C

Unloaded, the REF31xx can be operated on supplies down

to 5mV above the output voltage. All models are specified for

the wide temperature range of –40°C to +125°C.

APPLICATIONS

● PORTABLE, BATTERY-POWERED EQUIPMENT

● DATA ACQUISITION SYSTEMS

● MEDICAL EQUIPMENT
