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 I_Q: 50µA max

APPLICATIONS

● PORTABLE, BATTERY-POWERED EQUIPMENT

● DATA ACQUISITION SYSTEMS

● MEDICAL EQUIPMENT
