100ppm/°C, 50µA in SOT23-3  
CMOS VOLTAGE REFERENCE  
FEATURES  
DESCRIPTION  
The REF29xx is a precision, low-power, low-voltage dropout  
voltage reference family available in a tiny SOT23-3.  
MicroSIZE PACKAGE: SOT23-3  
LOW DROPOUT: 1mV  
The REF29xx’s small size and low power consumption  
(50µA max) make it ideal for portable and battery-powered  
applications. The REF29xx does not require a load capacitor,  
but is stable with any capacitive load.  
HIGH OUTPUT CURRENT: 25mA  
LOW TEMPERATURE DRIFT: 100ppm/°C max  
HIGH ACCURACY: 2%  
Unloaded, the REF29xx can be operated with supplies within  
1mV of output voltage. All models are specified for the wide  
temperature range, –40°C to +125°C.  
LOW IQ: 50µA max  
APPLICATIONS  
PORTABLE, BATTERY-POWERED EQUIPMENT  
DATA ACQUISITION SYSTEMS  
MEDICAL EQUIPMENT
