comparator mode applications.
In shunt regulator mode, the ZXRE160 simplifies the design of
isolated low voltage DC-DC regulators. With its low 0.6V FB pin, it can
control the regulation of rails as low 0.6V. This makes the part ideal
for state of the art microprocessor, DSP and PLD core voltage
POL converters.
The device open-collector output can operate from 0.2V to 18V and

regulated output voltage can be set by selection of two external

divider resistors. Separating the input from the open collector output
enables the ZXRE160 to be used to make low-cost low drop-out
regulators operating at low input voltages.
The ZXRE160 is available in two grades with initial tolerances of 0.5%
