Description
The RC0431A is a low-voltage 3-terminal adjustable
precision voltage reference regulator. It has an excellent
thermal stability over the standard commercial temperature
range. The output voltage can be set to any value between
Vref (1.24V) and 12V using two external resistors. The
RC0431A operates from a lower voltage (1.24V) than the
traditional shunt regulator references which operate from
2.5V. When used with an optocoupler, the RC0431A will be
an ideal voltage reference in an isolated feedback circuit for
use in switched-mode power supplies and modular DC-DC
converters. The RC0431A has a low output impedance of
active output circuitry offering a very sharp turn-on
characteristic. The RC0431A will be an excellent
replacement for low-voltage zener diodes in many
applications such as on-board regulation and adjustable
power supplies.
