? semiconductor components industries, llc, 2005 march, 2005 ? rev. 8 1 publication order number: NCV1009/d NCV1009 2.5 volt reference the NCV1009 is a precision trimmed 2.5 v 5.0 mv shunt regulator diode. the low dynamic impedance and wide operating current range enhances its versatility. the tight reference tolerance is achieved by on?chip trimming which minimizes voltage tolerance and temperature drift. a third terminal allows the reference voltage to be adjusted 5.0% to calibrate out system errors. in many applications, the NCV1009z can be used as a pin?to?pin replacement of the lt1009cz and the lm136z?2.5 with the external trim network eliminated. features ? 0.2% initial tolerance max. ? guaranteed temperature stability ? maximum 0.6 dynamic impedance ? wide operating current range ? directly interchangeable with lt1009 and lm136 for improved performance ? no adjustments needed for minimum temperature coefficient ? meets mil std 883c esd requirements ? extended operating temperature range for use in automotive applications ? ncv prefix, for automotive and other applications requiring site and change control ? pb?free package is available figure 1. application diagram 5.0 v?35 v 3.6 k v ref adj 10 k * gnd * 5.0% trim range trim if the external trim resistor is not used, the aadj. pino should be left floating. the 10k trim potentiometer does not effect the temperature coefficient of the device. device package shipping 2 ordering information NCV1009d soic?8 95 units/rail NCV1009dr2 soic?8 2500 tape & reel al = assembly location y = year w = work week soic?8 d suffix case 751 1 8 adj. pin gnd 18 v ref nc nc nc nc nc pin connections 2for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd8011/d.
