8.3.1 Supply Voltage

The REF35 family of references features an extremely low dropout voltage. For 10mA loaded conditions, a maximum dropout voltage is 250mV. Figure 6-34 shows a typical dropout voltage (VDO) versus load current. The device supports operation with input voltage range from VREF + VDO to 6V. The typical quiescent current is 650nA and maximum quiescent current over temperature is only 2.6μA. The low dropout voltage coupled with ultra-low current enable the operation across multiple battery powered applications.
