General Description
The APL1431L 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 APL1431L is an ideal voltage reference in isolated feedback circuits for 1.
24V to 12V switchingmode power supplies .
This device has a typical output impedance of 0.
1Ω .
Active output circuitry provides a very sharp turn-on characteristic , making the APL1431L excellent replacement...
