APL431 Description
Output voltage may be set to any value between VREF (2.5 V) and 20 V with two external resistors (See Figure 2). When used with an photocoupler, the APL431 is an ideal voltage reference in isolated feedback circuits for 2.5V to 12V switching-mode power supplies. This device has a typical output impedance of 0.1Ω.
