CALOGIC CA504

Current Regulator Diode
CORPORATION
CA500 Series / SST500 Series
FEATURES
• Simple Two Lead Current Sources
to 100 Volt Operation
• 1Zero
• Temperature Coefficient
• Simplifies Floating Current Sources
• No Power Supplies Required
GENERAL DESCRIPTION
Calogic’s current regulator diode is available in plastic TO-92
and surface mount SOT-23. The devices are selected for
narrow current ranges and are excellent choices for test
instrumentation and medical applications. With nominal
current ranges from 0.24mA to 4.7mA, all in 20% bands. The
devices allow the designer a cost effective method of
providing a current regulator with no power supply
requirements and lower part count. The lower current devices
operate at 1 volt.
