Description

The ZXRE160 is a 5-terminal adjustable shunt regulator offering

excellent temperature stability and output

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

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%

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.
