The ZXRE160AH5TA is a 5-terminal adjustable shunt regulator offeringexcellent temperature stability and output handling capability. Thisdevice offers an enhancement to the ZXRE060 part for use in acomparator mode applications.In shunt regulator mode, the ZXRE160AH5TA simplifies the design ofisolated low voltage DC-DC regulators. With its low 0.6V FB pin, it cancontrol the regulation of rails as low 0.6V. This makes the part idealfor state of the art microprocessor, DSP and PLD core voltagePOL converters.The device open-collector output can operate from 0.2V to 18V andregulated output voltage can be set by selection of two externaldivider resistors. Separating the input from the open collector outputenables the ZXRE160AH5TA to be used to make low-cost low drop-outregulators operating at low input voltages.The ZXRE160AH5TA is available in two grades with initial tolerances of 0.5%and 1% for the A and standard grades respectively. It is available inspace saving low profile 5 pin SC70/SOT353, thin TSOT25 and verysmall DFN1520 packages.
