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. http://onsemi.com SO–8 D SUFFIX CASE 751 8 1 Features • 0.2% Initial Tolerance Max. • Guaranteed Temperature Stability • Maximum 0.6 Ω Dynamic Impedance • Wide Operating Current Range • Directly Interchangeable with LT1009 and LM136 for Improved Performance • No Adjustments Needed for Minimum Temperature Coefficient • Meets Mil Std 883C ESD Requirements TO–92 Z SUFFIX CASE 29 1 2 3 PIN CONNECTIONS AND MARKING DIAGRAM NC 1 GND 1009 ALYWX NC NC 8 NC NC VREF ADJ.
