2.5V LOW POWERPRECISION REFERENCE SOURCE
ZRT025
DESCRIPTION
The ZRT025 is a monolithic integrated circuit providing
a precise stable reference voltage of 2.5V at 500A.
The circuit features a knee current of 150A and
operation over a wide range of temperatures and
currents.
The ZRT025 is available for surface mount
applications. This product 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 two temperature ranges
• 1 and 2% initial voltage tolerance versions available
• No external stabilizing capacitor required in most cases
• Low slope resistance
• No derating required at low temperatures
• SOT223 package
