up to 100mA. The device offers extended operating temperature range working from -55 to +125°C. VZ The output voltage may be set to any chosen voltage between 2.5 GND and 20 volts by selection of two external divider resistors. The devices can be used as a replacement for zener diodes in many VREF applications requiring an improvement in zener performance. (Top View)
