APL431L Overview
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 APL431L is an ideal voltage reference in isolated feedback circuits for 3V to 12V switching-mode power supplies. This device has a typical output impedance of 0.1W.
