ZRT025  
2.5V LOW POWER PRECISION REFERENCE SOURCE  
Description  
Pin Assignments  
The ZRT025 is a monolithic integrated circuit providing a  
precise stable reference voltage of 2.5V at 500μA.  
SOT223  
TRIM  
1
The circuit features a knee current of 150μA and operation  
over a wide range of temperatures and currents.  
GND  
VR

The ZRT025 is available for surface mount applications. This  
product 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.

(Pin 4 floating or  
connected to pin 2)  
Features  
Trimmable output  
Excellent temperature stability  
Low output noise figure  
-40 to 85°C operating temperature range  
1% initial voltage tolerance  
No external stabilizing capacitor required in most cases  
Low slope resistance  
No derating required at low temperatures  
SOT223 package  
Schematic Diagram  
This circuit will allow the reference to be trimmed over a wide range. The device is specified over a ±5% trim range.
