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 IQ: 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
