General Description

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

ref

(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 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.
