4.9V LOW POWER PRECISION REFERENCE SOURCE

ZRT050

The ZRT050 is a monolithic integrated circuit providing a precise stable reference voltage of 4.9V at 500µA. The circuit features a knee current of 150µA and operation over a wide range of temperatures and currents. The ZRT050 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.
• 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
• SOT223 small outline package
