CS1009/D
CS1009
2.5 Volt Reference
The CS1009 is a precision trimmed 2.5 V
±
5.0 mV shunt regulator
diode. The low dynamic impedance and wide operating current range
enhances its versatility. The tight reference tolerance is achieved by
on–chip trimming which minimizes voltage tolerance and temperature
drift.
A third terminal allows the reference voltage to be adjusted
±
5.0%
to calibrate out system errors. In many applications, the CS1009GZ
can be used as a pin–to–pin replacement of the LT1009CZ and the
LM136Z–2.5 with the external trim network eliminated.
