1 Description The SC1563 is a high performance positive voltage regulator designed for use in applications requiring very low dropout voltage at up to 5mA. Since it has superior dropout characteristics compared to regular LDOs, it can be used to supply 2.5 on motherboards or 2.8 on peripheral cards from the 3.3 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. A wide range of fixed output voltage options are available. In addition, the output voltage of every device can be adjusted between 1.2 and 4.8 using external resistors. The SC1563 comes in the space saving 5-pin SOT- 23 package.

6 Applications Information Introduction 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. Additional features include a shutdown pin to allow for a very low power consumption standby mode, and a fully adjustable output. Component Selection Input capacitor - a 1µF ceramic capacitor is recommended. This allows for the device being some distance from any bulk capacitance on the rail. Additionally, input droop due to load transients is reduced, improving load transient response. Additional capacitance may be added if required by the application. Output capacitor - a minimum bulk capacitance of 1µF, along with a.1µf ceramic decoupling capacitor is recommended. Increasing the bulk capacitance will improve the overall transient response. The use of multiple lower value ceramic capacitors in parallel to achieve the desired bulk capacitance will not cause stability issues. Although designed for use with ceramic output capacitors, the SC1563 is extremely tolerant of output capacitor ESR values and thus will also work comfortably with tantalum output capacitors. Noise immunity - in very electrically noisy environments, it is recommended that.1µf ceramic capacitors be placed from IN to GND and to GND as close to the device pins as possible. Thermal Considerations The power dissipation in the SC1563 is approximately equal to the product of the output current and the input to output voltage differential: P D IN ) I The absolute worst-case dissipation is given by: P DMAX) = INMAX ) MIN) ) IMAX ) + INMAX ) IQMAX ) For a typical scenario, IN = 3.3 ± 5%, = 2.5 and I = 5mA, therefore: INMAX) = 3.465, MIN) = 2.45 and I QMAX) = 15µA, Thus P DMAX) =.58W. Using this figure, and assuming T AMAX) = 7 C, we can calculate the maximum thermal impedance allowable to maintain T J 15 C: R TJMAX) TAMAX) ) 15 7) TH J A )MAX) = = PDMAX).58 = 157 C / W This should be achievable with the SOT-23-5 package 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. External voltage selection resistors - the use of 1% resistors, and designing for a current flow 1µA is recommended to ensure a well regulated output thus R2 12kΩ). 26 Semtech Corp. 6
