The ZXRE160 is a 5-terminal adjustable shunt regulator offering
excellent temperature stability and output handling capability. This
device offers an enhancement to the ZXRE060 part for use in a
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
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%
and 1% for the A and standard grades respectively. It is available in
space saving low profile 5 pin SC70/SOT353, thin TSOT25 and very
small DFN1520 packages.
