ZXRE060

Document number: DS33611 Rev. 6 - 2

Applications

Description

The ZXRE060 is a 5-terminal adjustable shunt regulator

offering

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

microprocessor/DSP

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.
