NCV1009
2.5 Volt Reference
The NCV1009 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 NCV1009Z
can be used as a pin-to-pin replacement of the LT1009CZ and the
LM136Z-2.5 with the external trim network eliminated.
