LT1009S8#PBF | Linear Technology

Voltage reference IC, LT1009S8#PBF, Linear Technology

The LT1009S8#PBF 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 the LT1009S8#PBF, a third terminal allows the reference voltage to be adjusted ±5% to calibrate out system errors. In many applications, the LT1009S8#PBF can be used as a pin-to-pin replacement of the LM136 and the external trim network eliminated.
