The SC563 provides fixed output voltages up to 300mA of load current per channel. Fixed output voltages for each output eliminates the need for external feedback resistors. The device has separate input, output and enable pins for each LDO channel. Using the lowest possible input voltage for each output voltage reduces the power loss for each rail. This improves overall package thermal performance and efficiency compared to single input voltage devices. The device has fast turn-on and turn-off voltage slew rate for fast system start up and reset response. Low quiescent current extends battery life. The SC563 family of devices provide protection circuitry such as short-circuit protection, un...
