AQT506/504
Current Regulator Diode
SC70-3, SOT23-3, TO92 Packages
Product Specification
Revision 1.0
July 10, 2004
General Description
The AQT506/504 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 AQT506/504 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.
