Description

The WSL431 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 (2.505V) and 20V with two external resistors (see Figure 2).


When used with a photocoupler, the WSL431 is an ideal voltage reference in isolated feedback circuits for 2.505V to 12V switching-mode power supplies.This device has a typical output impedance of o.1. Active output circuitry provides a very sharp turn-on characteristic, making the WSL431 excellent replacements for zener diodes in many applications, including on-board Regulation and adjustable power supplies.SOT-89 (Top View) TO
