Manufacturer Part Number
ZRT050GA1
Description
4.9V LOW POWER PRECISION REFERENCE SOURCE
Manufacturer
ZETEX [Zetex Semiconductors]
Datasheet
4.9V LOW POWER PRECISION REFERENCE SOURCE
DESCRIPTION
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
sh o w n in Fi g. 1. Th is f ac i li ty is u sed 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.
