Adjustable Precision Shunt Regulator

General Description

The APL1431 is a 3-terminal adjustable voltage ref-

erence 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 volt-

age reference in isolated feedback circuits for 2.5V

to 12V switching-mode power supplies. This device

has a typical output impedance of 0.1 . Active out-

put circuitry provides a very sharp turn-on

characteristic, making the APL1431 excellent replace-

ments for zener diodes in many applications, includ-

ing on-board regulation and adjustable power

supplies.
