Frequently Asked Questions
What is the output voltage and current rating of the UA79M05CKCS?
The UA79M05CKCS provides a fixed -5V regulated output with a maximum continuous output current of 1.5A, making it suitable for powering analog and mixed-signal circuits that require a stable negative supply rail.
What input voltage range does the UA79M05CKCS support?
The UA79M05CKCS accepts an input voltage range of -7V to -25V. The minimum input-to-output differential (dropout voltage) is 1.1V, so the input must be at least 1.1V more negative than the -5V output to maintain regulation.
What are typical applications for the UA79M05CKCS?
Typical applications include dual-supply op-amp circuits, audio amplifiers, instrumentation systems, and industrial power supplies. The device is ideal wherever a regulated -5V negative rail is needed alongside a positive voltage rail.
What package does the UA79M05CKCS come in, and is it RoHS compliant?
The UA79M05CKCS is housed in a Transistor Outline Vertical (TO-39 style) package with JESD-30 code R-PSFM-T3. It is Pb-free and RoHS compliant as indicated by the JESD-609 e3 code and Pbfree Code: Yes specification.
