CS5205A-1 Datasheet, PDF (1/8 Pages) Cherry Semiconductor Corporation – 5A Adjustable Linear Regulator

CS5205A−1
5.0 A Adjustable Linear
Regulator
The CS5205A−1 linear regulator provides 5.0 A at an adjustable
voltage with an accuracy of ±1%. Two external resistors are used to set
the output voltage within a 1.25 V to 13 V range.
The regulator is intended for use as a post regulator and
microprocessor supply. The fast loop response and low dropout
voltage make this regulator 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 regulator is fully protected against overload conditions with
protection circuitry for Safe Operating Area (SOA), overcurrent and
thermal shutdown.
The CS5205A−1 is pin compatible with the LT1084 family of linear
regulators but has lower dropout voltage.
The regulator is available in TO−220−3 and surface mount
D²PAK−3 packages.
