FUNCTIONAL DIAGRAM
DESCRIPTION
The ZXRE060 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 ZXRE060 to be
powered from an auxiliary rail, while controlling a master rail which is above the auxiliary rail voltage, or below
the minimum V
microprocessor/DSP/PLD cores.
As with other shunt regulators (and shunt references), the ZXRE060 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.
