DESCRIPTION

The REF29xx is a precision, low-power, low-voltage dropout

voltage reference family available in a tiny SOT23-3.

The REF29xx small size and low power consumption (50

µA

max) make it ideal for portable and battery-powered applica-

tions. The REF29xx does not require a load capacitor, but is

stable with any capacitive load.

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.

FEATURES

q MicroSIZE PACKAGE: SOT23-3

q LOW DROPOUT: 1mV

q HIGH OUTPUT CURRENT: 25mA

q LOW TEMPERATURE DRIFT: 100ppm/

q HIGH ACCURACY: 2%

q LOW I
