The device features extremely low dropout, high PSRR, ultralow output noise, and low quiescent current (190 mA typical per channel). When both outputs are disabled, the supply currents are reduced to less than 2 mA.

The output voltage is calculated using Equation 1: V OUT + VREF Ǔ ǒ1 ) R1 R2 (1) where VREF = 1.225 V (the internal reference voltage).

In the adjustable version, the addition of a capacitor, CFB, from the output to the feedback pin will also improve stability and transient response.
