50ppm/°C Max, 50µA in SOT23-3
CMOS VOLTAGE REFERENCE
FEATURES
DESCRIPTION
The REF30xx 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 REF30xx small size and low power consumption (50µA
max) make it ideal for portable and battery-powered applica-
tions. The REF30xx does not require a load capacitor, but is
stable with any capacitive load.
● HIGH OUTPUT CURRENT: 25mA
● HIGH ACCURACY: 0.2%
● LOW IQ: 50µA max
Unloaded, the REF30xx can be operated with supplies within
1mV of output voltage. All models are specified for the wide
temperature range, –40°C to +125°C.
●
EXCELLENT SPECIFIED DRIFT PERFORMANCE:
50ppm/°C (max) from 0°C to +70°C
75ppm/°C (max) from –40°C to +125°C
