AQ506/504
Current Regulator Diode
SC70-3, SOT23-3, TO92-2 Packages
Product Specification
Revision 1.4
July 31, 2006
General Description
The AQ506/504 is a 2-terminal current regulator
capable of delivering a constant current over a
wide voltage range, and requires no separate
voltage source or supporting components.
The AQ506/504 is a bipolar integrated circuit that
replaces legacy JFET devices.
Its low cost, small size, and simplicity makes the
current regulator diode ideal for applications
requiring an isolated constant current source.
