All parts have been tested and characterised using the following values and test circuit. /(" 7*/ Value CIN 100μF, 50V COUT 100μF, 10V $*/ 7065 $065 Voltage trimming The trimming (adjust) input on the device allows output voltage adjustment to within ±5%1 of the desired VOUT using a resistor with a value determined by the following equations. $0..0/ $0..0/ When open circuit, the output will be +5V. Shutdown A resistor (RD) between the trim pin and the output pin will adjust the output voltage between +5V to +1.8V. When the shutdown pin is shorted to Common, the device’s output will be disabled. To shutdown the device the pin should be taken below 0.8V using either an open collector pull down or by using isolated delay contacts. To enable the device output the shutdown pin should be left floating or taken no lower than +1.5V to a maximum of (+28V). 1 = (22 [1.028VO-1])-1-0.011 RD 7*/ 7065 /(" 7"%+ If the shutdown pin is to be connected to a long wire, it is recommended that a capacitor (10nF) decouples the shutdown pin to Common in order to avoid the risk of injecting noise into the device circuit. 3% $PNNPO 4% /(" A resistor (RU) between the trim pin and the Common pin will adjust the device output from +5V to +5.5V. ) ( 1 = (1.02VO)-1 -0.0455 RU 91 0'' 7*/ 7065 /(" 557"%+ 4% #$PSFRVJW 0/ O' PQUJPOBM ,û 36 4% $PNNPO All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified. 1.
