General Description
Applications
The APL431L is a 3-terminal low voltage adjustable precision reference with specified thermal stability over applicable commercial temperature ranges. Out-put voltage may be set to any value between V ref (1.24 V) and 20 V with two external resistors (see Fig-ure 2). When used with an photocoupler, the APL431L is an ideal voltage reference in isolated feed-back circuits for 3V to 12V switching-mode power supplies. This device has a typical output imped-ance of 0.1Ω. Active output circuitry provides a very sharp turn-on characteristic, making the APL431L ex-cellent replacements for zener diodes in many applications, including on-board regulation and ad-justable power supplies.
