A/AS535
2.5 V Precision Reference / Amplifier
Description
The AS535 is a three terminal adjustable shunt regulator
utilizing an accurate 2.5V bandgap reference. The AS535 is
functionally similar to an AS2431 except that the reference
and amplifier operate off of a seperate supply from the
output, allowing very low output voltges (0.1V Typically)
Because of its robust bipolar technology, the AS535 handles
a wide range of current, and holds off up to 18V so its use
is not limited to low power, low voltage systems. Significant
care has been taken to provide adequate AC bandwidth to
allow the AS535 as an amplifier in control systems and
power electronics. ASTEC also offers a 1.0% version of this
part, the A535.
