LT1009IZ#PBF

LT1009 is a precision trimmed 2.5V shunt regulator 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 this, a third terminal allows the reference voltage to be adjusted ±5% to calibrate out system errors. In many applications, this can be used as a pin-to-pin replacement of the LM136 and the external trim network eliminated. Typical applications are reference for 5V systems, 8-bit A/D and D/A reference, digital voltmeters, current loop measurement and control systems, power supply monitor.
