LT1009CMS8#PBF, Voltage References 2.5V Ref

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. • Maximum initial tolerance is 0.2%• Guaranteed temperature stability• Maximum 0.6ohm dynamic impedance• Wide operating current range• Directly interchangeable with LM136 for improved performance• No adjustments needed for minimum temperature coefficient• Reverse breakdown voltage is 2.5V at TA = 25°C, IR = 1mA• Average temperature coefficient is 25ppm/°C at 0°C <= TA <= 70°C• 8-lead plastic MSOP package• Temperature rating range from 0°C to 70°C
