The US2075 is a typical application in a flexible motherboard designed for Intel P55, P54, AMD K5, K6, as well as Cyrix M1 and M2 applications. It combines a PWM switcher controller and a 7.5A low dropout regulator, providing a total solution for dual supply processor applications.
The US1205 is an efficient linear voltage regulator from ON Semiconductor with better than 1% initial voltage accuracy, very low dropout voltage and very low ground current designed especially for hand held, battery powered applications. Other features of the device are; TTL compatible enable/ shutdown control input, current limiting and thermal shutdown. The US1205 is available in fixed and adjustable output voltage versions in a small SOT23-5 package.
