FEATURES
DESCRIPTION
The REF32xx is a very low drift, micropower,
2
• Excellent Specified Drift Performance:
low-dropout, precision voltage reference family
– 7ppm/°C (max) at 0°C to +125°C
available in the tiny SOT23-6 package.
– 20ppm/°C (max) at –40°C to +125°C
The small size and low power consumption (120μA
• Microsize Package: SOT23-6
max) of the REF32xx make it ideal for portable and
• High Output Current: ±10mA
battery-powered applications. This reference is stable
with any capacitive load.
• High Accuracy: 0.01%
The REF32xx can be operated from a supply as low
• Low Quiescent Current: 100μA
as 5mV above the output voltage, under no load
• Low Dropout: 5mV
conditions. All models are specified for the wide
temperature range of –40°C to +125°C.
