9.3.1 Supply Voltage

The REF35-Q1 family of references features an extremely low dropout voltage. For 10 mA loaded conditions, a maximum dropout voltage is 250 mV. Figure 7-25 shows a typical dropout voltage (VDO) versus load current. The device supports operation with input voltage range from VREF + VDO to 6 V. The typical quiescent current is 680 nA and maximum quiescent current over temperature is only 2.6 μA. The low dropout voltage coupled with ultral-ow current enable the operation across multiple battery powered applications.
