The APL431L is a 3-terminal low voltage adjustable
precision reference with specified thermal stability
over applicable commercial temperature ranges.
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. Active output circuitry provides
a very sharp turn-on characteristic, making the
APL431L excellent replacements for zener diodes
in many applications, including on-board regulation
and adjustable power supplies.
