Functional Block Diagram
The ZXRE160 differs from most other shunt regulators in that it
has separate input and output pins and a low voltage reference.
This enables it to regulate rails down to 600mV and makes the
part ideal for isolated power supply applications that use
opto-couplers in the feedback loop and where the open-collector
output is required to operate down to voltages as low as 200mV.
The wide input voltage range of 2V to 18V and output voltage
range of 0.2V to 18V enables the ZXRE160 to be powered from
an auxiliary rail, while controlling a master rail which is above the

auxiliary rail voltage, or below the minimum V
allows it to operate as a low-dropout voltage regulator for
microprocessor/DSP/PLD cores.
As with other shunt regulators (and shunt references), the
ZXRE160 compares its internal amplifier FB pin to a high
accuracy internal reference; if FB is below the reference then OUT
turns off, but if FB is above the reference then OUT sinks current
– up to a maximum of 15mA.
