Function Block Diagram
NEW PRODUCT
The ZXRD060 differs from most other shunt regulators in that it has separate input and output pins and a low voltage
reference. This enables it to regulate rails do wn to 600mV and makes th e part idea l for is olated po wer suppl y applications that
use opto-couplers in the feedback loop and where the open-collect or output is required to op erate down to v oltages as lo w as
200mV.
The wide input voltage range of 2V to 18V and output voltage rang e of 0.2V to 1 8V enables the ZXRD060 to be po wered from
an auxiliary rail, while controlling a master rail which is above the auxi liary rail volt age, or belo w the minimum V
allows it to operate as a low-dropout voltage regulator for microprocessor/DSP/PLD cores.
As with other shunt regulators (and shunt references), the ZXRD060 c ompares its internal amplifier FB pin to a high accurac y
internal reference; if FB is below the reference then OUT turns off, but if FB is above the reference then OUT sinks current –
up to a maximum of 15mA.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be affected by exposure
to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
transporting these devices.
