Features
* s s s s s s s s Low Voltage Low Temperature Coefficient Very Good Long Term Stability Low Slope Resistance Low RMS Noise Tight Tolerance High Power Supply Rejection Ratio 2-Lead TO-18 Metal Can Package ZN423 (CM-2) Fig.1 Pin connections (bottom view) ABSOLUTE MAXIMUM RATINGS Reference current, IREFApplications
* 5V, 0.5A Power Supply The circuit shown in Fig.5 is essentially a constant current source modified by the feedback components R2 and R3 to give a constant voltage output. The output of the ZN424P need only be 2V above the negative rail, by placing the load in the collector of the output transistor TZN423 Distributors
