PRODUCTION DATA
An op amp with a 1.25V offset input at the ADJUST pin provides easy output voltage or current programming (but not both). For current regulation applications, use a single resistor whose resistance value is 1.25V / IO and a power rating greater than (1.25V)2 / R. For voltage regulation applications, two resistors set the output voltage.
