AA Product Liine of Dioodes Incorpoorated ZZXRD060 00.6V DUALL ADJUSTAABLE PRECISION SHHUNT REGGULATOR Descriptioon Pin AAssignments The ZXRD0660 is a 10-tterminal adjusstable dual shunt ZXRD0060 FK regulator offeering excellent temperature sstability and ouutput (DFN26626P10) handling capability. The ZXXRD060 simplifies the design of isolated low voltage DC-DC regulators. With its low 00.6V PGND1 IN1 1 FB pin, it can control the reggulation of railss as low 0.6V. This makes it ideaal for state of the art microprocessor/DSP and N/C OUT1 PLD core volttage POL convverters. The device oopen-collector ooutput can opeerate from 0.2VV to FB1 GND 18V and reguulated output vvoltage can be set by selectioon of two external ddivider resistors. PGND2 IN2 Separating thhe input from thhe open collecctor output enaables the ZXRD0600 to be used to make low--cost low dropp-out FB2 OUT2 regulators operating at low iinput voltages. The ZXRD060 is availabble in two grades with innitial tolerances off 0.5% and 1%% for the A andd standard graades respectively. It is available in the space saving low prrofile Appplications 10 pin DFN26626P10 packagge.

Flag Floating or connect to GND Function Block Diagram 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 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-collector 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 voltage. This IN 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 above the reference then OUT sinks current up to a maximum of 15mA. 2 of 12 August 2011 ZXRD060 Diodes Incorporated www.diodes.com Document number: DS35359 Rev. 4 - 2 NEW PRODUCT
