MaxLinear, Inc. Voltage Regulators - Linear SPX1585AT-L-3-3

The SPX1585AT-L-3-3 is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 3.3V with a maximum output current of 5A. It features a low dropout voltage of 1.1V at full load, making it suitable for applications where efficient voltage regulation is required from a supply voltage as low as 4.8V. The device offers tight load and line regulation, ensuring stable output under varying conditions. This regulator includes built-in current and thermal limiting for protection against overload conditions. It is packaged in a standard 3-terminal TO-263 form factor, facilitating easy integration into various electronic designs. The SPX1585AT-L-3-3 is particularly well-suited for powering devices such as sound cards, PC supplies, and portable instrumentation, as well as serving as a post-regulator for switching power supplies.
