The APL1431L is a 3-terminal low voltage adjust-
able precision reference with specified thermal sta-
bility over applicable commercial temperature ranges
. Output voltage may be set to any value between
V
(see Figure 2) . When used with an photocoupler ,
the APL1431L is an ideal voltage reference in iso-
lated feedback circuits for 1.24V to 12V switching-
mode power supplies . This device has a typical
output impedance of 0.1
provides a very sharp turn-on characteristic , mak-
ing the APL1431L excellent replacements for zener
diodes in many applications , including on-board
regulation and adjustable power supplies .
