2.5V LOW POWER PRECISION REFERENCE SOURCE ISSUE 1 - OCTOBER 1995 ZRT025 DEVICE DESCRIPTION The ZRT025 is a monolithic integrated circuit providing a precise stable reference voltage of 2.5V at 500µA. The circuit features a knee current of 150µA and operation over a wide range of temperatures and currents. The ZRT025 is available in a 3-pin metal can package for through hole applications as well as SOT223 and SO8 packages for surface mount applications. Each package option 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 stabilising capacitor required in most cases • Low slope resistance • No derating required at low temperatures • TO18 package • SOT223 and SO8 small outline packages SCHEMATIC DIAGRAM R=VCC-VR IR RT=100k Optional trim facility This circuit will allow the reference to be trimmed over a wide range.

DEVICE DESCRIPTION

The ZRT025 is a monolithic integrated circuit providing a precise stable reference voltage of 2.5V at 500µA.

The circuit features a knee current of 150µA and operation over a wide range of temperatures and currents.

The ZRT025 is available in a 3-pin metal can package for through hole applications as well as SOT223 and SO8 packages for surface mount applications. Each package option 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.
