The APL431 is a 3-terminal adjustable voltage reference
with specified thermal stability over applicable commer-
cial temperature ranges. 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 feed-
back 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.
