ZXRE060
0.6V ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The ZXRE060 is a 5-terminal adjustable shunt regulator
offering excellent temperature stability and output
handling capability. The ZXRE060 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.
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 ZXRE060 to be used to make low-cost low
drop-out regulators operating at low input voltages.
The ZXRE060 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 SOT23 and very small
DFN1520 packages.
The ZXRE060 in TSOT23-5 has its OUT, GND and
FB pins matching the Cathode, Anode and reference pins
of the TL432 and TLV431 in SOT23-3, thereby facilitating
simple upgrade paths.
