SNAS781E October 2020 – July 2022 REF70
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.
