AQ506/504 Current Regulator Diode SC70-3, SOT23-3, TO92-2 Packages Product Specification Revision 1.4 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.
