? semiconductor components industries, llc, 2001 april, 2001 rev. 6 1 publication order number: cs1009/d cs1009 2.5 volt reference the cs1009 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 onchip 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 cs1009gz can be used as a pintopin replacement of the lt1009cz and the lm136z2.5 with the external trim network eliminated. features ? 0.2% initial tolerance max. ? guaranteed temperature stability ? maximum 0.6 w 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 figure 1. application diagram 5.0 v35 v 3.6 k w v ref adj 10 k w* gnd * 5.0% trim range trim http://onsemi.com device package shipping ordering information CS1009GD8 so8 95 units/rail cs1009gdr8 so8 2500 tape & reel a = assembly location wl, l = wafer lot yy, y = year ww, w = work week cs1009gz3 to92 2000 units cs1009gzr3 to92 2000 tape & reel to92 z suffix case 29 so8 d suffix case 751 1 8 adj. pin gnd 1 1009 alyw 8 v ref nc nc nc nc nc pin connections and marking diagram 1009 yww pin 1. adj. pin 2. v ref 3. gnd 1 1 2 3
