The SC1563ISK-3.0 is one member of the SC1563 series.It has the following features including 450mV dropout @ 500mA;Designed to operate with ceramic capacitors;Adjustable output from 1.200V to 3.3V;Multiple output voltage options (all parts also adjustable externally using resistors);Over current and over temperature protection;Enable pin;1A quiescent current in shutdown;Low reverse leakage (output to input);Full industrial temperature range.
The SC1563 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 500 milliamps. Since it has superior dropout characteristics compared to regular LDOs, it can be used to supply 2.5V on motherboards or 2.8V on peripheral cards from the 3.3V supply with no heatsink. Additionally, the SC1563 has a shutdown pin, to further reduce power dissipation while shut down. The SC1563 provides excellent regulation over variations in line, load and temperature.The SC1563 is available as a five terminal fixed or adjustable output voltage device with enable. The device is available in a 5-pin SOT-23 package and an 8-pin MSOP package for higher power dissipation/lower junction temperature.The SC1563 is intended for applications such as graphics cards where high current capability and very low dropout voltage are required. It provides a very simple, low cost solution that uses little pcb real estate and typically does not require a heatsink. Additional features include an enable pin to allow for a very low power consumption standby mode, and a fully adjustable output.
This should be achievable using pcb copper area to aid in conducting the heat away from the device. Internal ground/power planes and air flow will also assist in removing heat. For higher ambient temperatures additional board copper may be required. Use of the available MSOP-8 package will allow operation at full load where higher input to output voltage differentials exist.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).
