Description

The ZRT040 is a monolithic integrated circuit providing a precise stable reference voltage of 4.01V at 500μA. The circuit features a knee current of 150μA and operation over a wide range of temperatures and currents. The ZRT040 is available in a SOT223 package for surface mount applications. This device offers a trim facility whereby the output voltage can be adjusted as shown in the schematic diagram. This facility is used when compensating for system errors or setting the reference output to a particular value. When the trim facility is not used, the pin should be left open circuit.

Feature(s)

  • Trimmable output
  • Excellent temperature stability
  • Low output noise figure
  • Available in three temperature ranges
  • 1% initial voltage tolerance
  • No external stabilising capacitor required in most cases
  • Low slope resistance
  • SOT223 small outline packages
