Manufacturer Part Number
zrt040
Description
Zrt040 - 4.01v Low Power Precision Reference Source
Manufacturer
Zetex Semiconductors plc.
Datasheet
4.01V LOW POWER PRECISION REFERENCE SOURCE
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
sh o w n i n Fi g. 1. Th is f ac i li t y is used w h en
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.
