0.6V DUAL ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZXRD060 is a 10-terminal adjustable dual shunt
regulator offering excellent temperature stability and output
handling capability. The ZXRD060 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 it ideal for state of the art microprocessor/DSP and
PLD core voltage POL converters.

OUT1
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 ZXRD060 to be used to make low-cost low drop-out
regulators operating at low input voltages.

The ZXRD060 is available in two grades with initial
tolerances of 0.5% and 1% for the A and standard grades
respectively. It is available in the space saving low profile
10 pin DFN2626P10 package.
