3 V voltage reference with high PSRR

25 November 2009 Analogue, Mixed Signal, LSI

Maxim’s MAX6010 is a precision, low-power voltage reference offering a high PSRR of 51 dB at 2 kHz to ease design of applications with electrically noisy environments. In addition, it has a low 200 mV dropout voltage and 3 μA typical supply current that is virtually independent of supply voltage. This configuration avoids the wasted supply current of conventional shunt-mode references and eliminates the external resistor that they require. Packaged in a 2,9 x 2,3 mm SOT23, the device is well suited for portable and battery-operated applications such as battery-monitoring systems.

The MAX6010 operates with an input voltage from 3,2 V to 5,5 V and has an output of 3,0 V. The reference has an initial accuracy of ±0,2% (A grade) and ±0,4% (B grade), and temperature drift of 16 ppm/°C.
