... Output capacitor - Semtech recommends a minimum capacitance of 1µF at the output with an equivalent series resistance (ESR) of < 1 the SC553 has been designed to be used with ceramic capacitors, it does not have to be used with ceramic capacitors, allowing the designer a choice. Increasing the bulk capacitance will further reduce output noise and improve the overall transient response ...

... MAX ) With the standard SOT-23-5 Land Pattern shown at the end of this datasheet, and minimum trace widths, the thermal impedance junction to ambient for SC553 is 256°C/W. Thus no additional heatsinking is required for this example. The junction temperature can be reduced further (or higher power dissipation can be allowed) by the use of ...
