APL431
Adjustable Precision Shunt Regulator
Features
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 Vref (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.
