The NCV1009 is a precision trimmed 2.5 V ±5.0 mV shunt regulator diode. It has low dynamic impedance and wide operating current range. On−chip trimming minimizes voltage tolerance and temperature drift. A third terminal allows the reference voltage to be adjusted ±5.0% to calibrate out system errors.
The NCV1009 is a precision trimmed 2.5 V +5.0 mV shunt regulator diode designed with low dynamic impedance and a wide operating current range. It features on-chip trimming to minimize voltage tolerance and temperature drift, allowing for direct interchangeability with the LT1009CZ and LM136Z-2.5 in many applications.

The reference voltage can be adjusted by up to ±5.0% using an external trim resistor.
Yes, if the external trim resistor is not used, the 'ADJ. PIN' should be left floating.
