The APL431 is a 3-terminal adjustable voltage refer­ence with specified thermal stability over applicable
commercial temperature ranges. Output voltage may
be set to any value between V

(2.5 V) and 20 V with

ref

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. Active output cir­cuitry provides a very sharp turn-on characteristic,

making the APL431 excellent replacements for ze­ner diodes in many applications, including on-board
regulation and adjustable power supplies.
