PRODUCTION DATA
The REF pin is the output of a 5-V linear regulator that can be used to bias an opto-coupler transistor, primary side of an isolated gate driver or digital isolator, among other housekeeping circuits. The regulator output is internally current limited to IREF(LIM) (39-mA typical). The REF pin must be locally decoupled with a ceramic capacitor, the recommended range of values is from 0.1-µF to 10-µF.
