APL1431L Overview
The APL1431L is a 3-terminal low voltage adjustable precision reference with specified thermal stability over applicable mercial temperature ranges . Output voltage may be set to any value between VREF (1.24 V) and 20 V with two external resistors (see Figure 2) . When used with an photocoupler , the APL1431L is an ideal voltage reference in isolated feedback circuits for 1.24V to 12V switchingmode power supplies.
