11 Power Supply Recommendation

The REF70 family of references features a low-dropout voltage. These references can be operated with a supply

of only 50 mV above the output voltage for 0-mA output current conditions. The dropout voltage will vary with

the output current so refer to the dropout voltage to see typical dropout voltage requirements. TI recommends a

supply bypass capacitor ranging between 0.1 µF to 10 µF.

During start-up the REF70 can experience moments of high input current due to the output capacitors. The input

current can momentarily rise to ISC.
