A Product Line of Diodes Incorporated ZXRE160 0.6V ENHANCED ADJUSTABLE PRECISION SHUNT REGULATOR Description Pin Assignments
ZXRE160_H5 (SC70/SOT353) and The ZXRE160 is a 5-terminal adjustable shunt regulator offering ZXRE160_ET5 (TSOT25) excellent temperature stability and output handling capability. This T device offers an enhancement to the ZXRE060 part for use in a op vi op v ew i comparator mode applications.

In shunt regulator mode, the ZXRE160 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 the part 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 ZXRE160_FT4 (X2-DFN1520-6) regulated output voltage can be set by selection of two external
