Product Overview

The LT1009 series precision-trimmed Shunt Regulator features low dynamic impedance and a wide operating current range. The reference tolerance is achieved by on-chip trimming, which minimizes the initial voltage tolerance and the temperature coefficient, αVZ. Although the LT1009 needs no adjustments, a third terminal (ADJ) allows the reference voltage to be adjusted ±5% to eliminate system errors. In many applications, the LT1009 can be used as a terminal-for-terminal replacement for the LM136-2.5, which eliminates the external trim network. The LT1009 uses include 5V system references, 8-bit analog-to-digital converter (ADC) and digital-to-analog converter (DAC) references and power-supply monitors. The device also can be used in applications such as digital voltmeters and current-loop measurement and control systems.
  • Excellent temperature stability
  • Wide operating current range
  • Directly interchangeable with LM136
  • 0.6Ω Maximum dynamic impedance
