DESCRIPTION
The CL2431 is a three terminal adjustable voltage reference
designed to act as an open-loop error amplifier with a 2.5V
temperature compensated reference. Operating as a low
temperature coefficient zener which is programmable from
V
REF
to 18V with two external resistors while providing a wide
operating current range of 1.0mA to 100mA with a typical
dynamic impedance of 0.15
. As a shunt regulator the
device can be used as either a positive or negative voltage
reference. Active output circuitry provides a very sharp
turn-on characteristic, making the CL2431 an excellent
replacement for low-voltage zener diodes in many
applications, including on-board regulation and adjustable
power supplies.
