4.01V LOW POWER PRECISION REFERENCE SOURCE
ZRT040
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 Fig.1. 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.
FEATURES
• Trimmable output
• Excellent temperature stability
• Low output noise figure
• Available in three temperature ranges
• 1 and 2% initial voltage tolerance versions
available
• No external stabilising capacitor required in
most cases
• Low slope resistance
• SOT223 small outline packages
