4.0 A Adjustable, and
3.3 V and 5.0 V Fixed
Linear Regulators
The CS5204−x series of linear regulators provides 4.0 A at
adjustable and fixed voltages with an accuracy of
±1.0%
and
±2.0%
respectively. The adjustable version uses two external resistors to set
the output voltage within a 1.25 V to 13 V range.
The regulators are intended for use as post regulators and
microprocessor supplies. The fast loop response and low dropout
voltage make these regulators ideal for applications where low voltage
operation and good transient response are important.
The circuit is designed to operate with dropout voltages as low as
1.0 V depending on the output current level. The maximum quiescent
current is only 10 mA at full load.
The regulators are fully protected against overload conditions with
protection circuitry for Safe Operating Area (SOA), overcurrent and
thermal shutdown.
The regulators are available in TO−220−3 and surface mount
2
PAK−3 packages.

3. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output
voltage due to thermal gradients or temperature changes must be taken into account separately.
4. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package.
5. Dropout voltage is a measurement of the minimum input/output differentials at full load.
