lt1009 series 1 1009ff typical application features applications description 2.5v reference the lt ? 1009 is a precision trimmed 2.5v shunt regula- tor diode featuring a maximum initial tolerance of only 5mv. the low dynamic impedance and wide operating current range enhances its versatility. the 0.2% reference tolerance is achieved by on-chip trimming which not only minimizes the initial voltage tolerance but also minimizes the temperature drift. even though no adjustments are needed with the lt1009, a third terminal allows the reference voltage to be adjusted 5% to calibrate out system errors. in many applications, the lt1009 can be used as a pin-to-pin replacement of the lm136 and the external trim network eliminated. for a lower drift 2.5v reference, see the lt1019 data sheet. 2.5v reference n reference for 5v systems n 8-bit a/d and d/a reference n digital voltmeters n current loop measurement and control systems n power supply monitor l , lt, ltc and ltm are registered trademarks of linear technology corporation. all other trademarks are the property of their respective owners. n maximum initial tolerance: 0.2% n guaranteed temperature stability n maximum 0.6 dynamic impedance n wide operating current range n directly interchangeable with lm136 for improved performance n no adjustments needed for minimum temperature coef? cient n available in 8-lead so and msop packages and 3-lead to-92 package lt1009 output 3.6k 5v to 35v 10k* trim 1009 ta01 *does not affect temperature coefficient. 5% trim range output voltage temperature (c) C50 reference voltage (v) 2.53 2.52 2.51 2.50 2.49 2.48 2.47 25 75 1009 ta02 C25 0 50 100 125 typical guaranteed maximum guaranteed minimum
