10 IN1 Supply Input 1. Connect a 0.1 μF ceramic capacitor close to the device from IN1 to GND. Flag Floating or connect to GND Function Block Diagram The ZXRD060 differs from most other shunt regulators in t hat it has separate input and out put pins and a low voltage reference. This enables it to regulate rails down to 600mV and makes the part ideal for isolated power supply applications that use opto-couplers in the feedback loop and where the open-collect or output is required to operate down to voltages as low as 200mV. The wide input voltage range of 2V to 18V and output voltage range of 0.2V to 18V enables the ZXRD060 to be powered from an auxiliary rail, while controlling a master rail which is above the auxiliary rail voltage, or below the minimum V IN voltage. This 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 compares its internal amplifier FB pin to a high accuracy internal reference; if FB is below the reference then OUT turns off, but if FB is abov e the reference then OUT sinks current – up to a maximum of 15mA.
