General Description
The APL1431 is a 3-terminal adjustable voltage refer-
ence with specified thermal stability over applicable
commercial temperature ranges. Output voltage may
be set to any value between V
two external resistors (see Figure 2). When used with
an photocoupler, the APL1431 is an ideal voltage ref-
erence in isolated feedback circuits for 2.5V to 12V
switching-mode power supplies. This device has a typi-
cal output impedance of 0.1 . Active output circuitry
provides a very sharp turn-on characteristic, making
the APL1431 excellent replacements for zener diodes
in many applications, including on-board regulation and
adjustable power supplies.
